With a 2-inch head diameter and an overall height of 1 inch, it provides a secure, ergonomic grip for hand-tightening tasks. The knob features a 3\/8-24 female threaded insert with a 5\/8-inch hole depth and a 3\/4-inch hub diameter, allowing direct threading onto standard fastener shanks without additional hardware. Phenolic construction delivers chemical and heat resistance suitable for industrial and trade environments. The glossy black finish resists fading and wear under repeated handling.\u003c\/p\u003e\n\u003cp\u003eThis knob is suited for use on control panels, equipment covers, jigs, fixtures, and adjustment mechanisms found in HVAC units, electrical enclosures, and light industrial machinery. The female insert style allows installation directly onto threaded studs or bolts, making it a straightforward replacement or upgrade for existing manual-adjust hardware. The 3-arm profile balances grip surface area with clearance in tight panel layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-inch head diameter for comfortable hand grip\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 female threaded insert, 5\/8-inch hole depth\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hub diameter with female insert style mounting\u003c\/li\u003e\n  \u003cli\u003eGlossy coated phenolic construction — chemical and heat resistant\u003c\/li\u003e\n  \u003cli\u003e3-arm profile balances grip area with panel clearance\u003c\/li\u003e\n  \u003cli\u003eBlack gloss finish resists fading under repeated use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or retrofit hand knob for equipment with 3\/8-24 threaded studs or bolts requiring manual adjustment control.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools — thread the knob directly onto a 3\/8-24 male stud or bolt by hand.
