Gibraltar B5-31-G Fixed Handwheel Machine Handle

Product Description

The GIBRALTAR B5-31-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-shaped grip for secure manual operation and a chrome-plated finish for corrosion resistance. It accepts a 5/16-18 threaded stem that measures 9/16 inches in length. The overall assembled length is 3-3/16 inches, with a handle length of 2-5/8 inches. This type of handle is typically installed by maintenance technicians and machinists on valves, jigs, fixtures, and machine tool assemblies where a firm manual grip and repeatable positioning are required.

The B5-31-G is suited for light-duty manual control applications on machine tools, fixtures, and industrial equipment requiring a compact, threaded-stem-mounted grip. The bulb shape provides a comfortable gripping surface for frequent adjustments in production or maintenance environments. The chrome-plated carbon steel construction makes it appropriate for general shop use where moderate environmental exposure is expected.

Compatibility

Designed as an OEM-style replacement or upgrade handle for machine tools, fixtures, and industrial equipment that use a 5/16-18 threaded stem mounting interface.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard hand tools. Ensure the mating threaded boss or stem is clean and free of debris before threading on the handle. Apply appropriate thread-locking compound if vibration is expected in the application. De-energize or lock out any associated equipment before replacing handles on operating machinery per applicable OSHA lockout/tagout procedures.
