Gibraltar G10-3018-B Fluted Knob 3 Inch Phenolic

Product Description

The GIBRALTAR G10-3018-B is a fluted knob with a 3-inch diameter head, designed for manual adjustment and clamping applications in industrial, mechanical, and tooling environments. The knob features a female threaded insert sized at 3/8-16 and is constructed from phenolic material with a glossy finish. Phenolic offers good rigidity and resistance to oils and solvents, making this knob suitable for machine tools, fixtures, jigs, and similar equipment. Installation requires no special tools and is handled by maintenance technicians, machinists, and equipment assemblers.

This fluted knob is well suited for use on drill presses, milling fixtures, workholding setups, and general industrial equipment where a hand-tightened fastener is needed. The 3/8-16 female insert threads directly onto a compatible male-threaded stud or bolt. Its compact form and textured fluted profile allow for a secure grip and consistent hand torque without tools, making it practical for repeated adjustment cycles in production and maintenance settings.

Installation Notes

Installation is performed by machinists, maintenance technicians, or equipment assemblers. Thread the female insert onto a compatible 3/8-16 male stud by hand until snug. Do not use power tools to drive this knob, as over-torquing can crack the phenolic body. Ensure the mating stud threads are clean and free of debris before installation.
