Gibraltar 645290-G Fixed Handwheel Machine Handle

Product Description

The GIBRALTAR 645290-G is a fixed handwheel machine handle designed for industrial and mechanical equipment applications requiring a secure, manually operated grip. Built with a carbon steel bulb-shaped handle and a carbon steel threaded stem, this handle provides a firm, ergonomic hold for operators adjusting machinery, valves, or fixtures. The stem features a 7/16-14 thread, and the handle measures 11/16 inches in length with an overall assembly length of 3-29/32 inches. It is suited for use by machinists, maintenance technicians, and equipment service professionals who need a reliable, fixed-position handle for repeated manual adjustments.

This handwheel machine handle is appropriate for use on machine tools, industrial fixtures, jigs, and mechanical equipment where a threaded stem mount is required. The fixed design means the handle does not fold or rotate independently, making it well suited for applications where a permanent, rigid grip point is preferred. The 7/16-14 thread specification allows direct installation onto compatible threaded shafts or studs found on a wide range of standard industrial machinery.

Installation Notes

Installation is performed by maintenance technicians or machinists using standard hand tools. Ensure the mating threaded shaft or stud is clean and free of debris before threading the stem into place. Power down or de-energize any associated equipment before performing handle replacement or installation. Do not exceed the manual torque appropriate for carbon steel threaded fasteners at this thread size, and verify thread engagement is complete before returning equipment to service.
