Gibraltar 645285-G Fixed Handwheel Machine Handle

Product Description

The GIBRALTAR 645285-G is a fixed handwheel machine handle designed for use with 3/8-16 threaded stem applications. It features a bulb-shaped grip made from carbon steel, paired with a carbon steel stem measuring 9/16 inches in length. The overall assembly length is 2-11/16 inches. This handle is intended for industrial and mechanical equipment where a secure, hand-operable control point is needed. Machinists, maintenance technicians, and equipment assemblers typically install this type of handle on jigs, fixtures, machine tool components, and adjustable assemblies that require frequent manual positioning or clamping.

This handle suits light-duty to medium-duty machine applications in both shop and industrial environments. The threaded stem mount allows direct installation into tapped holes on equipment panels, fixtures, and machine frames. Its compact overall length makes it appropriate for space-constrained mounting locations. The fixed handwheel design means the grip does not rotate independently of the stem, making it well suited for applications that require direct torque transfer from hand to fastener.

Key Features

• 3/8-16 threaded stem for direct installation into standard tapped holes
• Bulb-shaped grip provides positive hand contact and control
• Carbon steel construction on both handle body and stem for durability
• Compact 2-11/16 inch overall length suits tight mounting spaces
• Fixed handle design transfers torque directly without grip rotation

Compatibility

Designed as a direct-fit replacement or new-installation handwheel handle for machinery, fixtures, and equipment with 3/8-16 threaded mounting points.

Installation Notes

Installation is performed by threading the stem directly into a 3/8-16 tapped hole on the equipment. Ensure the equipment is de-energized and any moving components are locked out before removing or installing handles on active machinery. Use standard hand tools appropriate for the mounting interface. Do not overtighten, as carbon steel stems can be susceptible to thread damage if excessive force is applied.
