The knob features a 2-inch head diameter and stands 1 inch high, with a 3\/4-inch hub diameter providing a solid grip surface. It uses a 1\/4-20 female insert style with a 3\/8-inch hole depth, making it a direct threaded fastener for bolts and studs. The glossy black phenolic construction offers good chemical resistance and a firm feel under hand torque. Licensed technicians, machine builders, and maintenance professionals use this type of knob as a tool-free adjustment point on panels, guards, and equipment enclosures.\u003c\/p\u003e\n\u003cp\u003eThis knob is suited for use in light industrial, HVAC equipment access panels, electrical enclosures, and mechanical assembly applications where a hand-operated threaded fastener is needed. The three-arm profile distributes grip force evenly and allows adequate torque without tooling. It is appropriate for both shop-floor assembly and field service environments where frequent panel removal or adjustment is required. The black glossy finish is consistent with standard industrial hardware aesthetics and resists minor surface wear.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-inch head diameter with three-arm profile for secure hand grip\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 female insert accommodates standard bolts and threaded studs\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hole depth provides positive thread engagement\u003c\/li\u003e\n  \u003cli\u003eGlossy coated phenolic construction for chemical resistance and durability\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hub diameter with 1-inch overall height for compact installation\u003c\/li\u003e\n  \u003cli\u003eBlack finish suits standard industrial and equipment panel applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or aftermarket three-arm knob for machinery, equipment panels, and fixtures using 1\/4-20 threaded hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tooling — thread the knob onto a 1\/4-20 bolt or stud by hand to the appropriate engagement depth. Ensure the mating thread is clean and free of debris before installation to avoid cross-threading the insert. Do not apply impact or power tools to this knob, as the phenolic body and insert are rated for hand torque only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Depth\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Phenolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Glossy Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: G10-3040AF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51691722375474,"sku":"G10-3040AF","price":43.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb9bf5209ea9967f3cf3752b70f9aecc.jpg?v=1788288880","url":"https:\/\/voomisupply.com\/products\/gibraltar-g10-3040af-phenolic-3-arm-knob-1-4-20-female-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
