Overtightening and undertightening screws on firearm components are both detrimental. Fortunately, it's easy to avoid both of these things with the FAT Wrench from Wheeler Engineering!

This wrench measures the torque when tightening screws on your firearms, allowing you to give them the perfect amount of force. You won't have to experience the frustration of stripped out threads or screws coming loose when firing! Nine different bits are included so that this tool can be used on a wide variety of fasteners. A plastic storage case will keep the tool and all of its components in one convenient place.

The FAT Wrench is one of the most valuable gun tools you can have in your set, although it can be used for any other mechanical application!
