Adjustable Support Screws
When working with large or flexible workpieces that could bow under machining pressure, use these screws as easy-to-install support points. Also known as jack screws or jig screws, they thread into a T-slot nut or threaded hole in the fixture to support or locate the workpiece above your machine table.

Spring-Loaded Work Supports
Slide these low-profile supports under a workpiece to provide support and reduce vibration. The slot in the center of the support allows for positioning at any angle before bolting it down to a machine table or fixture. Turn the handle to extend the spring-loaded plunger and lock it in place. For additional height adjustment, thread a screw or support button (sold separately) into the plunger.
Adjustable Side Stops
Adjust the horizontal screw to hold workpieces of varying sizes in precise positions. These stops thread into a hole in your fixture or machinery or into a T-slot nut for use on a machine table.
Swivel tips move in all directions to make maximum contact with angled and uneven workpieces.
