Gibraltar G10-0030-W Ball Knob Female Insert 1 in Phenolic

Product Description

The GIBRALTAR G10-0030-W is a phenolic ball knob with a female insert mount, designed for use on threaded shafts and fasteners in light industrial, machine tool, and equipment assembly applications. The knob measures 1 inch in diameter and 15/16 inch in height, with a 1/4-28 female threaded insert and a hole depth of 7/16 inch. The smooth black phenolic construction offers a firm, chemical-resistant grip surface suitable for repeated manual adjustment in shop and field environments. Machinists, equipment assemblers, and maintenance technicians are the primary installers of this hardware.

This knob is used wherever a compact, hand-operated adjustment point is needed on threaded machine shafts, jig fixtures, equipment panels, or fabricated assemblies. The 1/4-28 thread size suits fine-thread fastener applications common in precision equipment, light machinery, and instrumentation mounting. The 1/2 inch hub diameter provides a stable base on the mounting surface. The black phenolic body is resistant to oils and common shop solvents, making it practical for use in machine shop and industrial maintenance settings.

Installation Notes

Installation requires no special tools — thread the female insert onto a compatible 1/4-28 stud or shaft by hand until seated. Ensure the mating shaft does not exceed the 7/16 inch hole depth to avoid bottoming out the insert. Power down or de-energize any equipment before servicing adjustment knobs on live machinery. Follow applicable machine guarding and lockout/tagout procedures per OSHA and equipment manufacturer guidelines.
