The newest addition to the ever-expanding, iconic F.A.T. Wrench® family comes the F.A.T. Wrench AutoTorque, the first battery-operated screwdriver with an integrated torque limiter engineered specifically for the gunsmithing industry. This innovative screwdriver allows you to work faster when installing red dots, scope bases, scope rings, and action screws without sacrificing accuracy. Adjustment is simple, just set the torque between 5-65 in-lbs. on the easy-to-read digital display and get to work. The variable speed 200 RPM motor stops automatically when the desired torque is reached, safeguarding against fasteners being over-torqued or causing damage to your firearm. The rechargeable battery pack boasts a generous 2-hour continuous run-time on a single charge. Includes a 15-piece, black phosphate-coated 1/4” bit set that conveniently fits most common fasteners found on modern firearms. All the contents are neatly organized and secured in a premium latching hard case and stacks with other Wheeler sets for smart, convenient storage.
