Gibraltar 1RM8A206A8Z002G Fluted Knob Female Insert

Product Description

The GIBRALTAR 1RM8A206A8Z002G is a fluted knob with a female insert, designed for hand-tightening applications in mechanical assemblies, enclosures, and equipment panels. The knob features a 1.87-inch head diameter and is molded from thermoplastic elastomer, which provides a firm yet slightly compliant grip surface. The female insert accepts a 5/16-18 threaded fastener or stud. This type of knob is commonly installed by machine builders, maintenance technicians, and equipment assemblers who need a tool-free adjustment or clamping point in their builds.

This fluted knob is suited for light industrial, HVAC equipment panels, electrical enclosures, and general mechanical assemblies where hand-adjustable fastening is required. The thermoplastic elastomer construction holds up to repeated handling in shop and field environments. The 5/16-18 female thread makes it compatible with standard fractional threaded studs and bolts found in a wide range of domestic equipment builds and panel assemblies.

Installation Notes

Installation requires no special tools — the knob threads directly onto a 5/16-18 stud or bolt by hand. Ensure the mating stud is clean and free of debris before threading the insert. Do not use a wrench or power tool to drive this knob, as over-torquing can damage the thermoplastic elastomer body or strip the female insert. Verify thread engagement depth is sufficient for the application before placing the assembly back in service.
