The Wheeler F.A.T. Wrench (Firearm Accurizing Torque) brings perfect consistency to every screw on your rifle. This amazing, industry-standard handheld torque wrench lets you apply repeatable, accurate torque. Why is this important? Because precisely tightened screws and mounts prevent damage to optics and firearms and decrease the chances of failure in the field. Equipped with an adjustable torque range that delivers 10-65 in-lbs., it’s engineered to tackle a wide variety of common gunsmithing tasks like tightening scope bases and rings, action screws, and more with precision. The driver features a magnetized tip to prevent bits from falling out and a textured, rubber over-mold that improves ergonomics and grip while reducing hand strain during high torque applications. The 10 included bits are treated with a black phosphate coating that prevents rust and corrosion and extends tool life; guaranteeing that your tools will look great for years to come. All the contents are neatly organized and secured in a premium latching hard case that easily stacks on top of other Wheeler screwdriver sets for smart, convenient storage.
