Gibraltar KN5X-6X-B4----- Ball Knob 1-15/32 in Black

Product Description

The GIBRALTAR KN5X-6X-B4----- is a black polypropylene ball knob designed for hand-adjustment applications on machinery, fixtures, and equipment. With a diameter of 1.47 inches and a height of 1.40 inches, this knob provides a rounded grip surface that allows firm, comfortable manual actuation without tooling. The polypropylene construction resists common shop chemicals and moisture, making it suitable for light industrial and mechanical environments. It accepts multiple threaded hole configurations, giving it broad applicability across metric and unified thread fastener standards. Installed by machine builders, maintenance technicians, and assembly professionals wherever a secure, tool-free adjustment point is needed.

This ball knob is appropriate for use on jigs, fixtures, panels, and equipment enclosures in light industrial, manufacturing, and trade shop settings. Its multi-thread hole compatibility supports installation on threaded studs or threaded inserts ranging from 5/16-18 to 3/8-24 unified threads and M8 to M10 metric threads. The 0.71-inch hole depth accommodates standard stud engagement lengths. Typical applications include clamp handles, machine guards, and panel-mounted adjustment controls in both production and maintenance contexts.

Compatibility

Designed as an OEM-style replacement or direct-fit addition for equipment requiring a threaded ball knob in 5/16-18, 5/16-24, 3/8-16, 3/8-24, M8, or M10 thread sizes.

Installation Notes

Installation is performed by hand or with light tooling to thread the knob onto an existing stud or threaded insert. De-energize or lock out any equipment before replacing adjustment knobs on live machinery per applicable OSHA lockout/tagout procedures. Verify thread specification and engagement depth before seating the knob to avoid cross-threading the polypropylene hub. Do not exceed the torque limitations of the polypropylene body; this knob is intended for hand-adjustment service, not structural clamping under high mechanical load.
