Product Description

The GIBRALTAR KN6X-8X-B5--R-- is a red polypropylene ball knob designed for use with threaded fasteners in industrial, mechanical, and equipment assembly applications. The ball grip style provides a comfortable, secure hold for hand-tightening operations where tools are not practical. This knob measures 1.38 inches in diameter and 1.28 inches in height, with a hub diameter of 0.75 inches and a hole depth of 0.71 inches. It accepts multiple thread sizes, making it a versatile choice across a wide range of applications. Machinists, maintenance technicians, and equipment assemblers commonly install these knobs in production and field service environments.

This ball knob is suited for use on machine controls, jigs, fixtures, and industrial equipment where frequent manual adjustment is required. The polypropylene construction resists common shop chemicals and provides good durability in light-duty to medium-duty settings. The red color aids in visual identification on control panels and machinery. Its multi-thread compatibility allows use across both inch and metric fastener configurations without the need for inserts or adapters.

Installation Notes

Installation is performed by hand-threading the knob onto a compatible threaded stud or bolt. Ensure the mating thread size matches one of the supported hole configurations before installation.
