The knob body is molded from phenolic, a durable thermoset material that resists moderate heat and common shop chemicals. It measures 1-3\/8 inches in diameter and 1-9\/32 inches in height, with a 7\/16-20 threaded female insert and a hole depth of 3\/4 inches. The red color aids visual identification in multi-knob panel or machine setups. Technicians and maintenance professionals use this style of knob wherever a tool-free hand-tightened grip point is needed.\u003c\/p\u003e\n\u003cp\u003eThis ball knob is suited for use on machine tools, control panels, jigs, fixtures, and general equipment requiring a hand-adjusted knob on a threaded stud or shaft. The female insert design threads directly onto an existing male stud. Typical applications include industrial machinery, HVAC equipment access panels, and mechanical control assemblies where a compact, smooth-grip knob is appropriate. The 5\/8-inch hub diameter provides a defined seating surface against the mounting face.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale insert mount accepts 7\/16-20 threaded male stud\u003c\/li\u003e\n  \u003cli\u003ePhenolic knob body resists heat and common chemicals\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch diameter with smooth grip exterior\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch hole depth accommodates standard stud engagement lengths\u003c\/li\u003e\n  \u003cli\u003eRed color for quick visual identification on multi-knob assemblies\u003c\/li\u003e\n  \u003cli\u003eCompact 5\/8 inch hub diameter seats flush against mounting surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or aftermarket addition for any threaded application using a 7\/16-20 male stud that requires a hand-tightened ball knob with a female insert mount.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools — thread the knob onto the existing male stud by hand until seated firmly against the mounting surface. Ensure the mating stud thread is 7\/16-20 and that the engaged thread length does not exceed the 3\/4 inch hole depth. Disconnect or de-energize any associated equipment before replacing knobs on live control panels or powered machinery. Do not apply excessive torque, as phenolic bodies can crack under over-tightening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-9\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Depth\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Female Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrip Type\u003c\/strong\u003e: Smooth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Phenolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\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: G10-0033AC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51703714021682,"sku":"G10-0033AC","price":102.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60d5f40ed11570af5ab6db5d070bcdbe.jpg?v=1788418186","url":"https:\/\/voomisupply.com\/products\/gibraltar-g10-0033ac-ball-knob-female-insert-1-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
