A shaft collar including a body with a centrally located bore fits over an elongated shaft. An aperture extends laterally across the body in the vicinity of the bore. The aperture extends laterally into the body also, leaving an arcuate segment situated, radially, between the bore and the aperture. A set screw is advanced radially inwardly through the apertures to press against the arcuate segment and deflect same into engagement with the outer diameter of the elongated shaft. The aperture may possess an elliptical cross-section, an arcuate cross-section, or may assume a circular cross-section. The shaft collar can be made from metal or plastic since the tightening process is performed with zero relative motion between the collar and shaft, and therefore there will be no marring or scratching of the shaft. |
