The knob measures 1-3\/8 inches in diameter and 1-5\/16 inches in height, with a 3\/8-16 threaded insert and a 1\/2-inch hole depth. The smooth grip surface and black phenolic construction make it well suited for applications requiring a clean appearance and moderate hand torque. Machinists, maintenance technicians, and equipment assemblers install this type of knob on levers, jigs, guards, and adjustable components across light manufacturing and industrial settings.\u003c\/p\u003e\n\u003cp\u003eThis ball knob is used in residential and commercial equipment assembly wherever a removable or permanently mounted hand control is needed on a 3\/8-16 threaded stud or bolt. Typical applications include machine tool adjustments, panel-mounted controls, fixture clamping, and equipment guards. The female insert style allows the knob to thread directly onto an existing male stud, making it a common replacement or upgrade component in maintenance and assembly work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale insert mount accepts a 3\/8-16 male stud with 1\/2-inch engagement depth\u003c\/li\u003e\n  \u003cli\u003ePhenolic construction offers good chemical resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch diameter provides a comfortable grip for hand-tightening operations\u003c\/li\u003e\n  \u003cli\u003eSmooth grip surface for clean, snag-free operation\u003c\/li\u003e\n  \u003cli\u003eBlack finish blends with standard industrial and equipment panel aesthetics\u003c\/li\u003e\n  \u003cli\u003eHub diameter of 5\/8 inch provides a stable seating surface against mating components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation ball knob for equipment and machinery using a 3\/8-16 threaded stud mount.

De-energize or lock out any associated equipment before servicing adjustable components. Do not exceed recommended hand-tightening torque for phenolic knobs, as over-torquing can crack the body. Confirm stud length does not bottom out in the insert before the knob seats fully against the mating surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Female Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Size\u003c\/strong\u003e: 3\/8-16 x 1\/2 inches\u003c\/li\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: 1-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Depth\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Phenolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrip Type\u003c\/strong\u003e: Smooth\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: 0.0837 pounds\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: G10-0033-F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51714715681074,"sku":"G10-0033-F","price":32.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2933d6fb23bcbaf8344a56862a45ec7.jpg?v=1788505360","url":"https:\/\/voomisupply.com\/products\/gibraltar-g10-0033-f-ball-knob-female-insert-phenolic","provider":"Voomi Supply","version":"1.0","type":"link"}
