Molded from black phenolic with a gloss finish, this knob accepts a 3\/8-16 threaded stem and provides a 1\/2 inch thread engagement depth. The 3 inch head diameter gives technicians a broad grip surface for firm torque without tools. At 7\/8 inch hub diameter and 1-1\/8 inch overall height, the knob fits standard panel and machine control positions. It is suited for HVAC equipment panels, electrical enclosures, pump housings, and other assemblies where frequent manual adjustments are required.\u003c\/p\u003e\u003cp\u003eThis lobed knob is used wherever a threaded fastener or adjustment point needs to be operated by hand rather than with a wrench or driver. Common applications include control panel covers, access doors, jigs, fixtures, and equipment guards in light industrial, HVAC, and mechanical service environments. The phenolic construction handles moderate heat and resists common shop fluids, making it practical in mechanical rooms and equipment bays.
