August 22, 2008 -- The Fairloc® integral hub fastener consists of two slots that are machined into the hub, one radially the other angularly, to create a transverse wedge which remains attached to the solid portion of the hub on one side. The resultant cantilevered clamping section has a tapped hole to accept a cap screw which passes through a clearance hole in the solid portion of the hub, and into a threaded hole in the transverse wedge section. As the screw is tightened, the cantilevered section clamps the shaft securely. The screw can be tightened and released repeatedly without marring the shaft or affecting its torque-transmitting abilities.

The male side of the adapter consists of shafts ranging in diameter from .1247" to .4997" (3 mm to 12 mm). For instance, an adapter with a female side designed to accommodate a .2405" shaft has at the other end shafts with diameters of 1/8", 3/16", 1/4", or 3/8".
