The Royal Chuck Stop provides a simple, consistent method for locating short parts in a 3-jaw lathe chuck. The chuck stop enables short parts to project beyond the chuck jaws, providing clearance for facing operations.


The Royal Chuck Stop is very accurate—front and rear locating surfaces are parallel within +/- 0.0004". Because the Royal Chuck Stop eliminates the need to bore soft jaws, machine setup time is reportedly greatly reduced.

The captive, web-shaped design of the Royal Chuck Stop eliminates the dangers of using spacers and parallels that could come loose and be thrown from a spinning chuck. Three strong magnets further secure the stop to the chuck face.
