FEATURES: Knurled knob that exerts positive, repeatable force. Clockwise, the knob declutches and turns freely when you reach the desired torque. Counter-clockwise, the knob locks for positive retraction. Can be used as a controlled-torque nut, or as a thumb screw by installing a custom-made screw in the tapped hole.
ADJUSTMENT: To set desired force, first remove the outer cover screw at the side of the knob, to expose the adjustment screw. Next, insert a hex wrench to turn the adjustment screw until desired torque is achieved. Reinstall the outer cover screw when finished. Torque can be adjusted from .3 to .7 Nm, resulting in a contact force of 50-550 N, but these values are approximate. Force can vary +/- 30% depending on lubrication and other operating conditions.
SIZES: One knob size, available with tapped-hole sizes from 1/4"-20 to 1/2"-13 (M6 to M12 in metric) — see Dimensions page for part numbers.
MATERIAL: Body and knob > 12L14 steel, black oxide finish. Spring > 17-7PH stainless or music wire. |
