Set Shaft Collars

Set Screw Shaft Collars

Set screw shaft collars are a solid ring featuring a set screw that breaches the inside bore when tightened. The shaft collar fits over a shaft component and the set screw is tightened to hold the clamp in place. This style of collar relies completely on the frictional force applied by the set screw to maintain its position on a shaft. The set screw “bites” into the shaft causing a displacement of the shaft material to provide the holding power of the set shaft collar.
