The Warne® TW-1 Torque Wrench allows you to precisely tighten Torx® style screws to Warne's recommended torque setting of 25in/lb. A simple, breakaway design lets you know when the proper torque has been reached. Designed for both bases and rings, this unit is a must have when installing Warne bases, rings, and tactical mounting systems. The TW-1 features a comfortable grip design that offers enhanced control during scope and ring installation, so you won't slip and mar your firearm. Wrench includes a T-15 bit and is preset at 25in/lbs (non-adjustable); bit cannot be exchanged with another size.
