They contain hundreds of insulated butt splice connectors (ring, fork, and spade terminals kits are available too) with heat shrink insulation. A butt splice connector is a tube-shaped crimp connector used to join two wires end-to-end (in-line) by crimping each wire on either side. Our butt connectors are marine grade: made from tinned copper for high conductivity and corrosion resistance, and covered in adhesive-lined heat shrink. Crimp them onto your wires, then heat the insulation to shrink and seal the connection – resulting in a durable, vibration-resistant termination (crimped connections are highly resistant to vibration and thermal shock). These kits come in multiple piece counts (330 up to 580 pieces) to suit your needs. With Black Friday savings up to 25%, it’s a great chance to get a bulk supply of assorted connectors. Seize this deal to ensure you have the right connector for any wiring job – from automotive repairs to home electrical fixes – all at an unbeatable Black Friday price!

For those tackling high-current wiring, such as hooking up car audio systems, RV or boat batteries, or solar battery banks, this kit is a lifesaver. It includes an assortment of tinned copper battery cable lugs (various sizes for AWG 8, 6, 4, 2, and 1 gauge cables) plus matching pieces of 3:1 heat shrink tubing for insulation. These heavy-duty lugs are used to crimp thick cables to battery terminals or power studs. Each lug is made of pure copper (tin-plated) for maximum conductivity and corrosion resistance – essential for reliable high-amp connections. When you crimp a thick cable into one of these lugs and heat-shrink the tubing over the junction, you get a solid, low-resistance connection that can handle extreme current. (Crimping is actually preferred over soldering for battery lugs in many cases because a well-crimped joint is mechanically strong and avoids issues like solder brittleness.) Normally, assembling a set of lugs in all these sizes can be costly, but with our Black Friday sale you get the whole 220-pc kit at a great price. Ensure your heavy-gauge wiring is safe and secure – grab this battery lug kit now and save 20%. It’s an investment in electrical reliability for your vehicle or backup power system, at an unbeatable Black Friday discount. Don’t wait, because this deal is hot!

This self-adjusting wire stripping tool automatically adapts to the wire gauge you insert (within 24–10 AWG range) and strips off the insulation cleanly with a simple squeeze. No more guessing or nicking wire strands with a knife – this tool makes stripping wires quick, easy, and precise. It also has built-in cutting and crimping functions for added versatility. If you plan to use all the connectors and crimp tools you’re buying, you’ll need a good stripper to prep your wires. And trust us, once you use an automatic stripper, you’ll never want to go back to manual stripping with a pair of pliers or a blade. Add this wire stripper to your Black Friday haul – you’ll save time and frustration on every wiring job going forward, and you’ll save money today thanks to the Black Friday sale. It’s a small investment for a big boost in efficiency!

These are just a few of the doorbusters and top-rated products available in our Black Friday event. We’ve also got deals on other items like wire ferrule crimping kits, heat guns for shrink tubing, low-voltage landscape cables, and more – so browse our site to find all discounts.

Quick Buying Guide – How to Choose the Right Tools & Connectors (and Maximize Savings)

With so many great options on the table, you might be wondering what to pick, especially if you’re new to electrical work. This quick buying guide will help you understand the different product types on sale and how to choose the ones that fit your projects. We’ll also sprinkle in some pro tips to ensure you use these tools/connectors effectively. Even if you’re an experienced electrician, it can’t hurt to review the key points – and if you’re a beginner, this will definitely be useful. Let’s break it down by category:

1. Crimping Tools – Ratcheting vs. Others: If you don’t already have a good crimping tool, we highly recommend choosing a ratcheting crimping tool from our sale. Ratcheting crimpers (like the ones Haisstronica offers) ensure that you apply the correct pressure to fully deform the connector – they won’t release until the crimp is complete. This helps prevent partially crimped terminals, which can lead to loose connections or overheating. A basic non-ratcheting crimp plier can work for occasional use, but you have to judge the pressure manually and it may not be as consistent. Our ratchet crimpers also often come with interchangeable dies or adjustable tension, giving you flexibility to crimp various connector types (insulated, non-insulated, ferrules, etc.) with one tool. If you work with a range of wire sizes, consider the 6-in-1 crimping kit we highlighted – it’s versatile and cost-effective (one tool for many jobs). For specialized uses: We have dedicated crimpers for things like open-barrel terminals (common in automotive connectors and ignition systems) – these ensure you properly roll the “ears” of open-barrel connectors for a solid crimp. For example, when crimping spark plug wires or Delphi/AMP/Tyco style pins, an open-barrel crimper is essential to get that tight fold-over crimp that is gas-tight and vibration-proof. So, if you know you’ll be working on automotive wiring harnesses or replacing spark plug wire ends, consider adding our open-barrel terminal crimper to your toolkit (it’s on sale at 25% off). Lastly, for very heavy cables (like 1 AWG battery cables), a manual hand crimper might not handle the gauge – those jobs may require a hydraulic crimping tool or hammer crimper. Haisstronica offers lug crimping kits, but not the hydraulic tool itself; however, our copper lugs are compatible with standard hydraulic crimpers. So if you’re venturing into big-gauge territory, plan accordingly. Bottom line: pick a ratcheting crimper for most wire connector jobs, ensure it covers the wire gauge range you need (most of ours cover ~22–10 AWG which suits common automotive and household wiring), and grab any specialized crimper (like ferrule crimper or open-barrel crimper) if your projects call for it. With Black Friday pricing, you can afford to get the right tool now and it will pay off in better crimps and fewer bad connections. Invest now while prices are low – a good crimping tool will serve you for years, and you’ll thank yourself every time you make a perfect crimp!

2. Wire Connectors & Terminals – Choosing Types and Using Them: We offer a wide variety of wire connectors – understanding the types will help you select what you need. Common connector types include butt splices, ring terminals, spade (fork) terminals, bullet connectors, ferrules, and more. Here’s a quick rundown:

• Butt Splice Connectors: As mentioned, these join two wires end-to-end. Use them whenever you need to extend a wire or repair a break in a wire. If the connection will be in an area exposed to moisture (car underbody, boat, outdoor lights), go for heat shrink butt connectors (with adhesive lining) for a waterproof result. If it’s a dry location, standard insulated butt connectors or even non-insulated (with separate tape or heat shrink added later) can work. Tip: Always strip the right amount of insulation before crimping – ideally the bare wire should be just long enough to fully fill the connector’s metal barrel with no excess sticking out. This maximizes the contact area and ensures a strong crimp. Our connectors have translucent tubing so you can visually verify the wire is inserted correctly to the barrel’s end. And remember to use the correct crimp die (usually color-coded for red/blue/yellow insulation) to crimp butt connectors – a mismatched die can either not crimp tight enough or cut through the connector. Using the right tool from our kits will make this easy. And of course, take advantage of our Black Friday deal on butt connector kits to get a full assortment – you’ll be prepared for any splicing task at a great price.

• Ring Terminals and Spade Terminals: These are used to attach wires to screw posts or studs (like grounding screws, battery terminals, or equipment terminals). Ring terminals form a closed loop and are very secure (the screw has to be completely removed to detach the wire), whereas spade/fork terminals can slip under a screw without full removal (convenient for certain applications). We have insulated ring/spade terminals in various sizes (some in heat shrink form for extra protection, others with nylon or PVC insulation). Choose the size based on your wire gauge and the screw size. For example, a “#8 stud, 16-14 AWG ring terminal” means it fits a #8 screw and a 16-14 gauge wire. Make sure the pack you get matches your needs (our kits often include multiple sizes). These terminals are great for automotive work (connecting wires to car battery clamps, grounding to chassis, etc.) and household wiring of devices. When crimping these, again strip the wire appropriately and crimp using the insulated-terminal jaw of your crimper. A well-crimped ring terminal should have the wire firmly cold-welded inside – give it a gentle tug test after crimping to ensure it doesn’t pull out. If you use our heat shrink ring terminals, after crimping, use a heat gun on the insulation until it fully shrinks and the adhesive melts, sealing the wire end. The result will be a secure, waterproof connection – important for reliability (for instance, marine or automotive applications often require this to prevent corrosion). If you need a bunch of ring or spade terminals, consider our connector kits on sale – you’ll get an assortment and save money, a smart move while Black Friday sales are on.

• Ferrule Connectors: Ferrules are small metal sleeves (often with a colored insulating collar) used primarily for terminating stranded wires that will be inserted into screw clamp terminals (like those on circuit breakers, terminal blocks, or appliance connectors). When you crimp a ferrule onto a stranded wire, it essentially turns it into a solid pin – preventing stray strands from fanning out and ensuring a dependable connection under the screw. This is important because bare stranded wire under a screw can spread or even break, leading to loose connections or “cold flow” over time. Using ferrules avoids those issues: they provide a consistent, gas-tight end on the wire and eliminate strand fraying. If you work on control panels, audio equipment, or any devices with screw terminals, ferrules are your friend. Our ferrule crimping tool kits (also discounted for Black Friday) come with thousands of ferrule connectors in various sizes and a dedicated ferrule crimper that makes square or hexagonal crimps. They’re very easy to use – just strip about 8-10mm of insulation (depending on ferrule length), insert the wire into the ferrule, and crimp. The result is neat and safe. We have both uninsulated ferrules and insulated ferrules (with plastic color-coded collars) in our kits. Choose based on your wire AWG – kits typically cover from AWG 23 up to AWG 7 or larger. If you plan any projects like wiring up an Arduino to a terminal block, building a custom PC power supply harness, or doing home automation wiring, you’ll love having ferrules on hand. Since it’s Black Friday, scoop up a ferrule kit now – you’ll get a great price and you’ll drastically improve the quality of your wiring connections. It’s a small detail that yields professional results, and it’s even better when you save money on it!

• Solder Seal vs. Crimp Connectors: We offer both, and each has its use. Solder seal (heat shrink solder) connectors are extremely convenient for field repairs or if you don’t have a crimp tool handy – just insert the wires overlapping in the connector and heat with a heat gun. The solder will melt and bond the wires, and the tubing will shrink and seal. They create a decent joint that is water-resistant and strong if done properly. However, they do rely on the solder joint, which isn’t as vibration-proof as a well-done crimp (crimped connections remain mechanically robust under vibration, whereas soldered ones can develop stress points). Crimp connectors, on the other hand, when properly crimped, form a mechanical lock (essentially a cold weld) that is very vibration-resistant and has excellent conductivity. So, which to choose? For critical, high-vibration environments (e.g. engine bays, machinery), many professionals prefer crimp + heat shrink for the strongest connection. For quick fixes or lower-strain applications, solder seal connectors work great and save time. We recommend having both in your toolkit. You might use solder seal connectors for quick trailer light repairs or indoor gadget wiring, and crimped heat shrink connectors for your car’s wiring or boat wiring. Since both types are on sale, you can actually pick up kits of each and be prepared for anything. Black Friday is the perfect chance to experiment – grab a set of solder seal connectors and a set of crimp connectors, all at a discount, and see which you prefer in various scenarios. Either way, you’ll be equipped with reliable wire connector solutions at a price that’s a steal.

3. Supporting Tools & Accessories: Don’t overlook the other tools and supplies that make your electrical work easier. Black Friday is a great time to get these as well, since every little bit of savings helps. Some items to consider:

• Wire Strippers and Cutters: We mentioned the automatic wire stripper above. If you’re doing any wiring, a proper stripper is essential for clean, damage-free strips. If you prefer a manual style, we also have precision manual wire strippers for specific gauge ranges. Whichever you choose, ensure it can handle the range of wire sizes you use (most of ours cover 10-22 AWG or thereabouts). A built-in cutter is handy for trimming wires to length. Also, a separate cable cutter is useful if you’ll cut larger cables or need to make very clean cuts (for example, cutting a thick battery cable prior to crimping a lug – a dedicated cable cutter will give a clean cut without smashing the wire). Check out our hand tools section for any snips or cutters on sale. These may seem like small things, but quality does matter (nothing’s worse than a dull cutter squashing your wire or a cheap stripper nicking half the strands). With our Black Friday discounts, you can afford the better tools – and you’ll notice the difference in your work. Treat yourself to a good stripper/cutter now and enjoy stress-free wiring going forward!

• Heat Guns and Heat Shrink Tubing: If you opt for heat shrink connectors or tubing, you’ll need a heat source to shrink them. A heat gun is the safest and most effective tool – it blows hot air at a controlled temperature to evenly shrink tubing without burning it. We’ve got a compact electric heat gun in our lineup which might be on sale. You can also use it for other tasks (like heat shrink tubing, solder seal connectors, or even heat-shrink tubing for other insulation jobs). Speaking of heat shrink tubing, we have assorted tubing kits too – various diameters and colors, including marine grade with adhesive lining. These are great for insulating bare connectors (like if you use non-insulated butt splices or crimp a bare lug, you can slide heat shrink over it after), or for adding extra insulation to any connection. Make sure to choose the right shrink ratio (3:1 with adhesive is best for waterproof sealing, 2:1 for general use). If you’re grabbing our connector kits, you might already get some pieces included, but a supplementary kit of tubing can’t hurt, especially at a discount. Heat shrink supplies are the kind of thing you’re always glad to have in the drawer when you need them – and they’re inexpensive, especially with our Black Friday sale. So consider adding a heat shrink tubing assortment and a heat gun to your cart – you’ll be prepared to do neat, long-lasting insulation on all your connections, and you’ll get them for a song.

• Testers and Miscellaneous: While not the focus of this sale, ensure you have basic electrical testers (a multimeter, voltage tester, etc.) to verify your work. We mention this because you might see deals elsewhere (even Best Buy Black Friday deals or Home Depot promotions) on things like multimeters, outlet testers, or battery testers. It’s wise to have those tools alongside your crimpers and connectors. A quick plug: our store mostly specializes in connectors and wiring tools, but we do have some toolkits that include extras like screwdrivers, pliers, etc. If you’re just starting out, an electrician’s toolset or kit might be a good choice – you get a collection of tools in one package (some of our kits bundle a crimper, stripper, screwdriver, and connectors together). Check the Tool Kits section for any DIY electrician starter kits on sale. They make excellent gifts too for anyone you know who’s into tinkering or could use a home wiring fix-it kit. If you see one on sale this Black Friday, snag it – it could be the all-in-one solution for a newbie electrician, and you’ll save money compared to buying tools individually.

4. Consider Your Project Needs (Plan Ahead): Lastly, think about upcoming projects or repairs you have in mind. Black Friday is a once-a-year chance to get these items at a lower cost, so it pays to anticipate. Are you planning to add landscape low-voltage lighting in your yard? If so, grab that discounted landscape wire spool and some heat shrink connectors now. Will you be installing a car amplifier or doing automotive wiring upgrades? Make sure you have a good wire crimper, an assortment of automotive connectors (maybe our waterproof spade and ring terminal kit), and some extra fuses/terminals – you might find those in our catalog too. Maybe you’re eyeing a solar panel setup for which you’ll need to crimp MC4 solar connectors – our solar connector crimp tool is on sale and will ensure you crimp those MC4 pins correctly (MC4 connectors require a precise crimp, different from regular connectors). Or perhaps you’re a marine enthusiast redoing a boat’s wiring – definitely stock up on our marine grade heat shrink connectors and a quality ratchet crimper; the saltwater environment demands the best connections and we’ve got the IP67 waterproof-rated gear for that. In short, use this opportunity to assemble a toolkit and supply stash that prepares you for all the electrical tasks you foresee. The best black friday deals are the ones that set you up for success in future projects without busting your budget. And if you’re unsure, our customer support (and various guide articles on our blog) can always help you choose the right item.
