Gibraltar 645275-G Fixed Handwheel Machine Handle

Product Description

The GIBRALTAR 645275-G is a fixed handwheel machine handle designed for industrial and trade applications requiring a secure, hand-operated grip on threaded assemblies. Built with a carbon steel bulb-shape handle body and a carbon steel threaded stem sized at 1/4-20 thread pitch, this handle provides reliable manual control on equipment, fixtures, and machinery. The stem measures 7/16 inches in length, and the overall assembled length reaches 1-23/32 inches. It is installed by machinists, maintenance technicians, and equipment fabricators wherever a compact, fixed-grip handwheel is needed.

This handle is suited for use in light industrial, manufacturing, and mechanical assembly environments. It is a common fitment on jigs, fixtures, machine tool components, and fabricated equipment panels where a threaded stem mount is already in place. The fixed handwheel design eliminates a spinning handle, making it appropriate for applications where a stationary grip is preferred for consistent torque application by hand.

Key Features

• Fixed handwheel design with bulb-shape handle body for secure manual grip
• 1/4-20 threaded stem mount for direct installation into compatible threaded bores
• Carbon steel construction on both handle and stem for durability in industrial settings
• Compact overall length of 1-23/32 inches suits confined equipment spaces
• 7/16-inch stem length accommodates standard threaded mounting depths
• Single-piece fixed configuration requires no adjustment or assembly before use

Compatibility

Designed as an OEM-style replacement or direct-fit addition for machinery, fixtures, and equipment using a 1/4-20 threaded stem mount with a fixed handwheel handle configuration.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard hand tools. Before installation, ensure the mating threaded bore is clean and free of debris, and confirm the thread pitch matches 1/4-20 to avoid cross-threading. Thread the stem into the bore by hand first, then tighten to a snug fit appropriate for the application without over-torquing carbon steel components. De-energize or lock out any equipment before servicing or replacing handles on active machinery per applicable OSHA lockout/tagout procedures.
