The Wheeler F.A.T. Wrench is a torque-limiting screwdriver built to take the guesswork out of mounting scopes, action screws, and other critical firearm components. Whether you're bedding a rifle scope, securing ring caps, or working on guard screws, this tool prevents the most common mistake: over-tightening. It's designed for hunters, shooters, gunsmiths, and anyone who wants their optics and hardware seated exactly right, without stripping threads or cracking precision parts.

The wrench's adjustable torque range runs from 10 to 65 inch-pounds in 1 inch-pound increments, giving you the precision control needed across a wide variety of firearm applications. You get 10 phosphate-coated S2 tool steel bits hardened to 56–58 Rockwell C—tough enough to handle repeated use without dulling or breaking. The ergonomic design makes it comfortable to grip and control, even during longer sessions at the bench. Everything ships in a custom-molded storage case that keeps the wrench and bits organized and protected, so nothing gets lost and the tool stays ready in your shop or range bag.

If you've ever stripped a scope ring screw or wondered whether you'd tightened something enough—or too much—this is the tool that ends that anxiety. It's a small investment that pays for itself the first time it saves you from having to order replacement parts or start over on a build.
