Use Fix It Sticks' All-in-One Torque Driver to tighten down scope rings, mounts, actions screws, etc. while in the field, at the range, or at home, with +/- 10% accuracy. You'll never over or under tighten critical components again. It's easy to use, too. Turn the drive handle until the hash mark lines up with the torque value you need (from 15 - 65 in-lb) and you're ready to get to work. The All-in-One Torque Driver accepts any standard 1/4" bit, fits into any standard 1/4" driver and integrates perfectly with Fix It Sticks tools and our T-Way Driver (not included).
