Gibraltar 645205-G Fixed Handwheel Machine Handle

Product Description

The GIBRALTAR 645205-G is a fixed handwheel machine handle designed for use with press fit stem mounting. Built with a carbon steel bulb-shaped handle body and a carbon steel stem, this component provides a reliable manual grip point for machine tool adjustments, jigs, fixtures, and industrial equipment. The stem measures 7/16 inches in length, and the handle has an overall length of 1-23/32 inches (approximately 1.75 inches). Licensed machinists, maintenance technicians, and tool-and-die professionals typically install this type of handle on precision equipment requiring repeated manual positioning.

This handle is suited for industrial and commercial machine tool applications where a compact, fixed-position grip is needed. The press fit stem mount allows for straightforward installation into a prepared bore without threading. Typical applications include manual feed mechanisms, clamping fixtures, and adjustment knobs on milling machines, lathes, drill presses, and similar equipment. Its bulb shape provides adequate grip surface in confined spaces where larger handles are impractical.

Installation Notes

Installation is performed by qualified maintenance technicians or machinists. Before installing, power down and lock out the machine per OSHA lockout/tagout procedures. The press fit stem should be pressed into a clean, properly sized bore using an arbor press or similar controlled-force tool — do not drive with a hammer, as this may damage the stem or bore alignment. Confirm bore diameter matches the stem before pressing to avoid loosening or interference fit failure.
