Product Description

The GIBRALTAR 5B60B933A8Z001G is a 5-point lobed knob constructed from thermoplastic elastomer (TPE) in a black finish. It provides a firm, ergonomic hand grip for manual adjustment, locking, or positioning tasks on threaded fastener assemblies. The knob features a 5/16-18 threaded stem with 1.5 inches of thread length, making it a direct-fit control knob for equipment panels, jigs, fixtures, and machinery. With a head diameter of 2.26 inches and an overall height of 1.09 inches, it offers a well-proportioned grip surface. Technicians and maintenance professionals install this knob where tool-free hand adjustment is required.

This lobed knob is suited for light industrial and commercial applications including equipment enclosures, control panels, machine guards, and fixture assemblies. It is appropriate for any installation requiring a hand-operable 5/16-18 threaded knob. The TPE material provides grip in both dry and lightly contaminated environments. HVAC, electrical, and general maintenance trades commonly use this type of hardware during panel assembly or equipment servicing.
