Molded from phenolic with a gloss finish, this knob delivers a firm, chemical-resistant grip surface that holds up in demanding shop and field environments. The knob features a 2.0-inch head diameter and a 1\/2-20 threaded hole with a 5\/8-inch thread depth, allowing direct installation onto compatible threaded studs or bolts without additional hardware. A hub diameter of 7\/8 inch and an overall height of approximately 1-5\/32 inches keep the profile compact while providing adequate torque leverage for hand tightening.\u003c\/p\u003e\u003cp\u003eThis lobed knob is suited for use on jigs, fixtures, machine guards, enclosures, and adjustment mechanisms where a tool-free, repeatable hand-tighten connection is required. The 4-lobe geometry distributes finger pressure evenly, reducing operator fatigue during repeated adjustments. Its phenolic construction makes it appropriate for environments with moderate heat, solvents, or oils. Maintenance technicians, equipment assemblers, and industrial service professionals commonly specify this style of knob for panel-mount and fixture applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-point lobed profile for secure hand grip and even torque distribution\u003c\/li\u003e\n\u003cli\u003ePhenolic material offers chemical resistance and moderate heat tolerance\u003c\/li\u003e\n\u003cli\u003eGloss finish provides a clean, professional appearance on finished assemblies\u003c\/li\u003e\n\u003cli\u003e1\/2-20 threaded hole with 5\/8-inch thread depth for direct stud or bolt mounting\u003c\/li\u003e\n\u003cli\u003eCompact 7\/8-inch hub diameter and 1-5\/32-inch overall height for space-constrained installations\u003c\/li\u003e\n\u003cli\u003e2.0-inch head diameter delivers adequate leverage for firm hand tightening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-mount replacement or new-installation lobed knob for any assembly using a 1\/2-20 threaded stud or bolt requiring a 4-point phenolic hand knob.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no tools beyond hand pressure in most applications; ensure the mating stud or threaded post is clean and free of debris before threading on the knob. Verify thread engagement depth does not exceed the 5\/8-inch hole depth to avoid bottoming out against the knob hub. For equipment service applications, de-energize or lock out the machine before adjusting or replacing hand knobs on any moving or adjustable component.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Type\u003c\/strong\u003e: Lobed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1-5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size (Thread)\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 0.625 inches (5\/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: Gloss Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162801\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: G10-2830BH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51690263609650,"sku":"G10-2830BH","price":91.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3fc0454947a0ea95ef52e1c8006e09b0.jpg?v=1788267899","url":"https:\/\/voomisupply.com\/products\/gibraltar-g10-2830bh-lobed-knob-2-in-4-point-phenolic-black","provider":"Voomi Supply","version":"1.0","type":"link"}
