Originally designed for Nightforce Optics Turret Screws, the 4 in-lb Miniature Torque Limiter with 3 Bits from Fix It Sticks includes a Torx 6 bit, a 5/64" Hex bit, and a 1.5mm Hex bit. The torque limiter accepts any standard 1/4" hex bit (or screw/bolt head) and fits into any standard 1/4" hex driver. With a ±6% accuracy, the limiter makes an audible click when the 4 in-lb limit is reached, and the limiter will slip, preventing further torque from being applied to your gear to protect your tools from damage.
