Gibraltar 5A01A204A8Z002G Lobed Knob 4-point 10-32 Black

Product Description

The GIBRALTAR 5A01A204A8Z002G is a 4-point lobed knob molded from thermoplastic elastomer (TPE) for use on threaded fastener applications requiring tool-free manual adjustment. The knob features a 1.4-inch head diameter and a 10-32 threaded blind hole with a 0.58-inch thread depth, accepting standard 10-32 screws and studs. The TPE construction provides a firm yet compliant grip surface that resists slipping under hand torque. At 0.02 pounds, it is lightweight and suited for panel-mounted controls, equipment covers, and adjustable assemblies in HVAC, electrical, or light mechanical enclosures.

This lobed knob is used wherever a 10-32 threaded stud or screw requires repeatable hand-tightening without tools. Typical applications include service panels, access covers, filter housings, and adjustable mounting brackets in residential and light commercial equipment. The 4-lobe profile distributes grip force evenly and suits confined spaces where larger diameter knobs would interfere with adjacent components. Black TPE coloring blends with standard equipment finishes and provides contrast for quick visual identification during service calls.

Key Features

• 4-point lobed profile enables tool-free hand tightening in tight spaces
• 1.4-inch head diameter with 0.56-inch hub diameter and 0.18-inch hub height
• 10-32 threaded hole with 0.58-inch thread depth accommodates standard 10-32 studs and screws
• Thermoplastic elastomer construction provides grip compliance and chemical resistance
• Overall height of 0.68 inches keeps a low-profile footprint on the mounting surface
• Lightweight at 0.02 pounds — minimal added mass to panel or enclosure assemblies

Compatibility

Designed for use with 10-32 threaded studs and screws in panel, enclosure, and equipment cover applications requiring manual adjustment knobs.

Installation Notes

Installation requires no special tools — thread the knob onto a 10-32 stud or screw by hand and tighten finger-tight to the required position. Ensure the mating stud thread length does not exceed the 0.58-inch hole depth to avoid bottoming out before the assembly is secure. Power down or de-energize any equipment before removing or reinstalling access panels or covers on which this knob is mounted. Do not use power tools to drive this knob, as over-torquing will strip the threaded insert.
