The knob measures 1-3\/8 inches in diameter and 1-9\/32 inches in height, with a smooth grip surface and a red finish for easy visual identification. The female insert accepts a 1\/4-20 threaded fastener, making it compatible with standard machine screws and threaded studs. Machinists, equipment assemblers, and maintenance technicians install this type of knob wherever a secure, hand-operated grip is needed on a threaded shaft or panel-mounted stud.\u003c\/p\u003e\n\u003cp\u003eThis ball knob is suited for use on machine tools, jigs, fixtures, control panels, and general industrial equipment where repeated manual adjustment is required. The phenolic construction provides good resistance to heat, chemicals, and mechanical wear in typical shop and plant environments. The female insert style allows the knob to be threaded directly onto an exposed stud or screw without requiring a through-hole, making it a practical choice for blind-mount applications. The compact hub diameter of 5\/8 inch keeps the profile low-clearance in tight assembly layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale insert mount accepts 1\/4-20 threaded fasteners for direct stud or screw installation\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch diameter phenolic ball provides a firm, smooth grip surface\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hole depth accommodates standard stud engagement lengths\u003c\/li\u003e\n  \u003cli\u003eRed color aids visual identification in multi-knob panel layouts\u003c\/li\u003e\n  \u003cli\u003ePhenolic material offers resistance to heat, shop chemicals, and wear\u003c\/li\u003e\n  \u003cli\u003eCompact 5\/8 inch hub diameter suits tight-clearance mounting locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-installation ball knob for equipment and machinery using 1\/4-20 threaded studs or machine screws requiring a female insert style knob.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDe-energize or lock out any equipment before servicing or replacing knobs on control panels or powered machinery, following applicable LOTO procedures. Thread the knob onto the stud by hand until snug; do not over-tighten phenolic hardware as the material can crack under excessive torque. A general-purpose hand tool may be used to hold the stud during installation if needed. Verify thread engagement does not exceed the 3\/8 inch hole depth to avoid bottoming out and stripping the insert.\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: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Phenolic\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: 1-9\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Depth\u003c\/strong\u003e: 3\/8 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\u003eGrip Type\u003c\/strong\u003e: Smooth\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: G10-0033-T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51695924805938,"sku":"G10-0033-T","price":48.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25739c4fb4aaf35a76053d3ae7f0651b.jpg?v=1788339452","url":"https:\/\/voomisupply.com\/products\/gibraltar-g10-0033-t-ball-knob-female-insert-1-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
