Wheeler Engineering F.A.T. Wrench AutoTorque Features The Wheeler F.A.T. Wrench AutoTorque is built around a variable speed 200 RPM motor paired with an integrated torque limiter a combination that automatically stops the driver once the desired torque is reached. That automatic cutoff safeguards against fasteners being over-torqued or damaging a firearm removing the guesswork that comes with a standard screwdriver or manual torque wrench. An easy-to-read digital LCD screen displays torque settings in 0.1 in-lb increments across a 10 to 65 in-lb range covering the common torque specs for red dots scope bases scope rings and action screws. A max setting rapidly switches the tool to full power for removing stubborn stuck fasteners when precision is no longer the priority. A detachable lithium-ion battery pack delivers 2 hours of continuous run-time on a single charge and recharges through a USB-C port with a quick-check LED battery status indicator built in. Four ultra-bright LEDs illuminate the workspace making it easier to see fastener heads in dim shop lighting or in the field. The kit includes a 15-piece black phosphate-coated 1/4 inch bit set that conveniently fits most common fasteners found on modern firearms all organized in a premium latching hard case. That case stacks with other Wheeler screwdriver sets letting gunsmiths and hobbyists build out a complete organized torque-driver toolkit over time. Wheeler Engineering F.A.T.
