The Wheeler FAT Wrench is a handheld torque wrench for firearms work. It is adjustable from 10 to 65 inch-pounds, so you can tighten scope bases, rings and other small fasteners to a set, repeatable value instead of guessing by feel.
Over-tightening ring screws can crush a scope tube or strip threads. Under-tightening lets mounts shift under recoil, and then the zero wanders. A torque wrench solves both problems: set the value from the manufacturer's spec, turn until the wrench tells you to stop, and every screw ends up the same.

Tip: always look up the torque value from the scope, ring or mount maker first, since ring caps and base screws often have different specs. Tighten ring screws in a cross pattern a little at a time so the gaps stay even.
