Description

Wheeler's 100-Piece Professional Gunsmithing FAT Wrench Screwdriver set is the kit that belongs on every gunsmithing bench. The well though-out bit selection will put an end to burred, buggered, and busted up screws on any gun that comes your way. The bits make up the heart of any screwdriver set, and Wheeler's are the finest available. They bits are made from S2 tool steel and hardened to 56-58 Rockwell "C". Unlike other screwdriver suppliers, Wheeler's engineers measured the screws on over one hundred modern and antique firearms to make sure that we offered bits for every situation. To top it off, this kit includes the FAT (Firearms Accurizing Torque) Wrench, which is used to apply precise inch-lb. pressure on all of your screws.

    • Excellent kit, must have for firearms enthusiasts
Style: 100 Piece
Very nice kit with high quality bits. Case is heavy duty and everything fits securely. I have been using wheeler products for a long time and they are still great! This kit is a must if you dabble with an array of firearms & optics. Torque driver indicator could be marked clearer but that’s splitting atoms honestly. Keeps you from over-torquing & stripping small fasteners. While not as extensive, this is the next best thing to fix-it sticks kits and a fraction of the cost ... show more

Style: 100 Piece
I absolutely love this Wheeler 100-piece gunsmithing screwdriver set. It has everything I need in one place, including both a torque driver and a standard driver, which makes it incredibly versatile for different jobs. Great quality from a trusted brand, the tools feel solid and well made, and the whole set comes at a really good price for what you get. It’s been heavily used with not a single issue. This has quickly become a go-to kit on my bench. ... show more

    • Nice set of tools for the price
Style: 100 Piece
Solid set for working on firearms and optics. The torque driver is very user friendly. I read some customers having issues with the clasp on the case all the parts come in. I found it to be robust enough, though. I wouldn’t be throwing it in the toolbox of your pickup to rattle around but it seems sturdy enough. ... show more

As of this review, I've had the set for around a month and a half. I've used it several times, and, for the most part, it's been a good buy. It contains everything you see in the pictures and the torque wrench works like it's supposed to. Like the subject says though, I've had some pieces break. The first thing to break was the magnet inside the torque wrench. It split in half. The top half came out stuck to the bottom of a bit. I have not been rough on the tools; no banging or beating on things. I've just used it to torque screws on firearms and attachments. The second thing to break was one of the bits. It just broke off inside a torx screw. This was more concerning than the magnet because it makes me think some of the other bits could be brittle. Maybe the pieces that broke were part of a bad batch, but I'd be lying if I said I'm not a little concerned. I've included pictures of the things that broke. As of now I'm giving it a 3 star rating because it has been useful. However, be aware that some of the pieces may fail over time. If I have other pieces break, then I'll come back and update this review. ... show more
