Gibraltar B6-50-G Revolving Handwheel Machine Handle

Product Description

The GIBRALTAR B6-50-G is a revolving handwheel machine handle designed for manual adjustment and positioning on industrial machinery and equipment. Built with a carbon steel bulb-shape handle and a carbon steel threaded stem, this handle measures 4 inches in handle length with an overall length of 4-13/16 inches. The stem uses a 1/2-13 thread size, providing a secure, standard fit on compatible threaded shafts and machine components. A chrome-plated finish adds corrosion resistance and a clean appearance. This type of handle is commonly installed by millwrights, machine technicians, and maintenance personnel on equipment requiring frequent manual operation or fine-position adjustment.

This revolving handwheel handle suits light industrial and general machine tool applications where operators need a firm, comfortable grip during repeated rotational adjustments. The revolving bulb knob reduces hand fatigue during extended use. Typical installation scenarios include machine tool tables, jigs, fixtures, and feed mechanism controls in shop or production environments where a threaded stem mount is required.

Key Features

• 1/2-13 threaded stem for direct mounting on compatible machine shafts
• Revolving bulb-shape handle reduces operator hand fatigue during repeated adjustments
• 4-inch handle length with 4-13/16 inches overall length
• Carbon steel construction for durability in light industrial use
• Chrome-plated finish for corrosion resistance and clean appearance
• 13/16-inch stem length fits standard threaded machine ports

Compatibility

Designed as a standard replacement or upgrade revolving handwheel machine handle for equipment using a 1/2-13 threaded stem mount in light industrial and machine tool applications.

Installation Notes

Installation is performed by threading the stem directly onto a compatible 1/2-13 threaded shaft on the target machine. Power down and de-energize all equipment before servicing any mechanical handles or adjustment mechanisms. Verify thread engagement is fully seated and that the handle rotates freely without binding before returning equipment to service. Use standard hand tools only — do not overtighten, as the carbon steel stem can be damaged by excessive torque.
