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.

  • Everything you need in one solid kit
Style: F.A.T. Wrench Screwdriver Set
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: F.A.T. Wrench Screwdriver Set
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

  • Extensive selection of tools but low quality finish
Style: F.A.T. Wrench Screwdriver Set
I purchased this tool kit for working on my firearms. I have yet to not find the tool needed to mount a scope or assemble a new AR lower or check torque on fasteners before going out to the gun range. My only grip, and this is why I gave it four stars, is the coating on the tools. I've had my tool set for around 6 months and the finish on the torx tips tools has already worn-off. I can see the metal on the tip of the torx attachments. This isn't an inexpensive set of tools so I expect a more durable finish on the tools. Other than the low quality finish, this is a good set of tools. ... show more
