FEATURES: Knurled knob that exerts positive, repeatable force. Clockwise, the knob declutches and turns freely when you reach the desired torque. Counterclockwise, 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. Made in USA.
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 6 inch-lbs, resulting in a contact force of 10 to 125 lbs, 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. |
