J.w. Winco 5T20A11/E Adjustable Clamping Handle 5/16-18

Product Description

The J.W. WINCO 5T20A11/E is a threaded stud adjustable clamping handle designed for secure, tool-free clamping in industrial and mechanical assemblies. The handle mounts via a 5/16-18 threaded stud with a stud length of 0.79 inches and an overall length of 2.74 inches. The steel handle arm features a ball-end style with a 20-degree arm angle and a black oxide finish, providing a firm grip and corrosion resistance in workshop and production environments. Licensed electricians, millwrights, machine builders, and maintenance technicians install this type of handle on jigs, fixtures, guards, and adjustment mechanisms where repeated manual clamping and release is required.

This adjustable clamping handle is suited for use in light industrial machinery, assembly fixtures, equipment guards, and adjustment points on fabrication tooling. Its compact profile, with a body height of 1.32 inches and a body diameter of 0.83 inches, makes it a practical fit in confined mounting locations. The plastic body components with a natural finish pair with the steel handle arm for a balance of weight reduction and mechanical strength. This part is commonly installed in OEM machine builds and field service retrofits across manufacturing, woodworking, and general mechanical trade applications.

Installation Notes

Installation is performed by threading the stud directly into a prepared 5/16-18 tapped hole; no special tools are required for mounting. De-energize and lock out any machine before replacing or adjusting clamping handles on powered equipment. Verify thread engagement depth against the 0.79-inch stud length to ensure secure seating without bottoming out. Follow applicable machine safety standards and equipment manufacturer guidelines during installation.
