PRECISION WORM
AND GEAR MECHANISM
#1 SWIVEL SHOE T-WRENCH
When holding the workpiece, the worm can turn the gear but the gear cannot turn the worm. Thus, the clamp cannot loosen. Light alloy swivel shoe provides protection against marring workpiece. It is removable and free to swivel. It is secured by spring-loaded balls and a variety of shoes are available. 8mm hex bal is used to tightened Mono-Bloc to riser or to table; socket is used to clamp workpiece.
