Torque Spec
Also: Inch-Pounds
The manufacturer's recommended tightening force for ring and base screws, applied with a calibrated torque wrench in inch-pounds for repeatable mounting.
A torque spec is the precise force, almost always given in inch-pounds, that a maker calls for when tightening the fasteners on an optical mount. Guessing by feel is risky, because too little clamp lets the scope shift under recoil while too much can crush the tube, strip threads, or warp the scope rings. A small calibrated torque wrench removes the guesswork and applies the same load to every screw.
Following the spec on both the rings and the scope base screws produces an even, predictable clamp that supports a clean install. It pairs naturally with ring lapping, since lapped rings spread that torque across a broad contact band rather than a few high spots. Consistent, correct torque is also one of the foundations of reliable return to zero, because a mount that never moves is a mount that always comes back to the same point.
