100 TPI Adjustment Screws


KD.37 knobs can be added to a hex-head AJS screw. The KD.37 has two slots for an Allen wrench to increase the adjustment sensitivity.

Position Sensitivity

Smallest difference in movement that can be discriminated. Typically, your fingertips are sensitive enough to distinguish 0.5°–1° rotations of an adjustment screw — in some cases much less. Therefore, when you see the term sensitivity this indicates the angular change of an optic associated with a 1° turn of the screw.
