Gibraltar GLH-535-G Gear Lever Knob Type C 5/16-18

Product Description

The GIBRALTAR GLH-535-G is a Type C gear lever knob with a taper end, designed for use in mechanical positioning, indexing, and clamping applications where a secure hand-adjustable grip is required. The knob features a stainless steel shaft paired with a phenolic knob body, combining corrosion resistance with a durable, heat-tolerant grip surface. The stem thread is 5/16-18, the shaft diameter measures 5/16 inches, and the knob diameter is 0.98 inches. Thread length is 0.51 inches and handle length is 1.5 inches, making this a compact lever suited for tight machine envelopes. Machinists, equipment assemblers, and maintenance technicians are the primary installers.

This gear lever knob is intended for use on machine tools, jigs, fixtures, and industrial equipment where hand-operated adjustment is needed. The Type C taper end configuration provides positive engagement on tapered shaft applications. The 5/16-18 thread stem allows direct installation on standard threaded bosses found across a wide range of light to medium-duty machinery. The phenolic knob body withstands moderate heat and light chemical exposure common in shop environments.

Installation Notes

Installation is performed by maintenance technicians or equipment assemblers. Power down and de-energize all associated equipment before servicing lever knobs on any machine tool or fixture. Thread the 5/16-18 stem onto the receiving boss by hand before applying tool torque to avoid cross-threading. Inspect the taper engagement on the shaft before final tightening to confirm full seating.
