Gibraltar 1RM8B944A8Z001G Fluted Knob Threaded Stem

Product Description

The GIBRALTAR 1RM8B944A8Z001G is a fluted knob with a threaded stem, designed for hand-tightening and manual adjustment applications across industrial, mechanical, and equipment assembly environments. The knob features a 1.87-inch head diameter and is molded from thermoplastic elastomer, which provides a firm, tactile grip surface and resistance to repeated handling. With a 3/8-16 threaded stem and a thread length of 1.75 inches, it installs directly onto standard threaded fastener interfaces without tools. Technicians and assembly professionals working on panel controls, fixtures, jigs, or equipment enclosures will find this a practical hardware solution.

This fluted knob is suited for use on machinery panels, control enclosures, test fixtures, and general industrial equipment where tool-free manual adjustments are required. The thermoplastic elastomer construction makes it appropriate for both light-duty shop environments and applications where some exposure to oils or solvents is expected. It is a single-piece, ready-to-install component sold individually and is compatible with any assembly that accepts a 3/8-16 threaded interface.

Compatibility

Designed as a direct-fit replacement or new-install threaded knob for any equipment or fixture assembly using a standard 3/8-16 threaded interface.

Installation Notes

This knob is intended for hand installation onto a 3/8-16 threaded stud or bolt. Before installing or replacing the knob, ensure the equipment or panel is powered down or de-energized if the knob interfaces with an electrical control. No special tools are required for installation; thread the stem in by hand to the appropriate engagement depth. Avoid over-tightening, as the thermoplastic elastomer hub can deform under excessive torque.
