Gibraltar 645280-G Fixed Handwheel Machine Handle

Product Description

The GIBRALTAR 645280-G is a fixed handwheel machine handle designed for use with threaded stem mounting applications in industrial and mechanical equipment. The handle features a bulb shape grip made from carbon steel, paired with a 7/16-inch-long carbon steel threaded stem sized at 5/16-18 thread pitch. Overall assembly length is 2-5/32 inches. This handle is a standard replacement or new-installation component suited for machinery, equipment panels, and enclosures where a secure, fixed grip point is required. Machinists, maintenance technicians, and industrial equipment installers are the typical end users.

This handle is appropriate for use on machine tools, industrial enclosures, jigs, fixtures, and general mechanical assemblies that require a reliable fixed-position handwheel grip. The 5/16-18 threaded stem allows for straightforward installation into standard tapped holes found across a wide range of production and maintenance equipment in both light industrial and commercial settings.

Compatibility

Designed as an OEM-style replacement or direct-fit component for machinery and equipment assemblies requiring a 5/16-18 threaded stem fixed handwheel handle.

Installation Notes

Installation is performed by maintenance technicians or machinists as part of equipment assembly or service. Power down and de-energize any equipment before servicing panels or enclosures where this handle will be installed. Thread the stem into the corresponding tapped hole by hand first to confirm proper thread engagement before applying a wrench or tool to avoid cross-threading. Verify that the tapped hole depth accommodates the full stem length to ensure a flush, secure fit.
