It is designed for use as a manual control or adjustment knob on equipment panels, machinery, and industrial fixtures where a threaded 3\/8-16 female insert is required. The tapered profile provides a secure, ergonomic grip for hand-tightening applications. With an overall length of 2.48 inches, a head diameter of 1.6 inches, and a base diameter of 1 inch, this knob is sized for standard panel and equipment mounting tasks. It weighs 0.5 pounds and is sold individually. Installers working on control assemblies, HVAC equipment panels, or light machinery will find this a direct-fit replacement or new-installation component.\u003c\/p\u003e\n\u003cp\u003eThis tapered knob is suited for residential and commercial equipment panels, control cabinets, and machinery where hand-adjustable fastening points are needed. The female insert design accepts a 3\/8-16 threaded stud or screw, making it compatible with a wide range of standard threaded hardware used across HVAC, electrical, and general industrial applications. The thermoplastic construction offers resistance to light chemical exposure and everyday handling in shop or field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale insert mount accepts 3\/8-16 threaded hardware\u003c\/li\u003e\n  \u003cli\u003eHole depth of 0.51 inches accommodates standard stud engagement\u003c\/li\u003e\n  \u003cli\u003eTapered head profile for secure hand-grip operation\u003c\/li\u003e\n  \u003cli\u003eThermoplastic construction — lightweight and corrosion-resistant\u003c\/li\u003e\n  \u003cli\u003eBlack finish — 1.6 inches head diameter, 1 inch base diameter\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.48 inches with a head height of 2.50 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation knob for equipment panels and machinery using standard 3\/8-16 threaded studs or screws.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by equipment technicians or panel assemblers during maintenance or retrofit work. Power down or de-energize any equipment before replacing control knobs on live panels. Thread the knob onto the 3\/8-16 stud by hand and tighten to a snug fit — avoid using tools that could crack the thermoplastic body. Verify thread engagement does not exceed the 0.51 inch hole depth to prevent bottoming out on the stud.\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\u003eHole Depth\u003c\/strong\u003e: 0.51 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 2.50 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Thermoplastic\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: 0.5 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: KN6C----S5--S21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51693222166834,"sku":"KN6C----S5--S21","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67eb6438ad6edcda2d97666ba4e8691c.jpg?v=1788309217","url":"https:\/\/voomisupply.com\/products\/gibraltar-kn6c-s5-s21-tapered-knob-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
