Swivel Ball End Screws & Ball End Feet

Screw Clamps

Swivel Ball End Screws are heavy-duty clamping screws designed for use with separate Ball End feet to create a robust two-piece swivel assembly. The ball end of the screw rotates 360° within the mating foot, allowing the foot to achieve full contact with the workpiece surface during tightening. Unlike conventional threaded swivel foot assemblies, the foot is retained on the ball end by a cross pin rather than threading, providing increased strength and durability in demanding clamping applications. The foot itself does not swivel but rotates freely around its axis to minimize surface marring during setup and adjustment.

The screw features a square design that permits high torque application using a wrench or driver, enabling secure clamping in heavy-duty fixturing and workholding. The precision-ground ball end ensures smooth rotation and reliable engagement with the corresponding foot. This design is ideal for applications requiring greater clamping forces and longer service life than standard swivel screw assemblies.
Swivel Ball End Screws are available in thread sizes from 1/2-13 to 1"-8 with multiple length options in each size. Ball End feet are ordered separately and correspond to specific screw thread sizes. All components are made in USA."
