The M-Type Shaftlock rotating-component fastener is used as a locking device for rigidly mounting hubless gears, sprockets, pulley, cams, or thinwalled components onto an inch or metric shaft. Tightening the nut of the two-part fastener causes the slotted sleeve to contract and grip the shaft, clamping the part to the sleeve at the same time. Available sizes include 0.375, 0.5, 0.625-in. shafts, as well as 10, 14, and 16-mm shafts.
