The knob features a polypropylene inner core with a thermoplastic elastomer (TPE) overmold, combining a rigid structural body with a softer, grippy outer surface that improves hand torque without tools. The head diameter measures 2.48 inches, providing a wide grip surface for gloved or bare-hand operation. The 1\/2-13 threaded stem with a 1.5-inch thread length allows secure fastening to standard threaded shafts or inserts in panels, fixtures, and assemblies.\u003c\/p\u003e\u003cp\u003eThis lobed knob is suited for use on machinery panels, enclosures, jigs, fixtures, and adjustment mechanisms where frequent hand-tightening or loosening is required. The matte black finish reduces glare and provides a clean appearance in both shop and field environments. It is appropriate for light-duty to medium-duty clamping and positioning applications in manufacturing, HVAC equipment, and industrial assembly. The 8-lobe profile distributes grip force evenly, reducing operator fatigue during repeated adjustments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-point lobed profile for high hand torque without tools\u003c\/li\u003e\n\u003cli\u003eThermoplastic elastomer overmold over polypropylene inner core for durable, comfortable grip\u003c\/li\u003e\n\u003cli\u003e2.48-inch head diameter provides a wide, easy-to-grasp surface\u003c\/li\u003e\n\u003cli\u003e1\/2-13 threaded stem with 1.5-inch thread length for standard hardware compatibility\u003c\/li\u003e\n\u003cli\u003eMatte black finish resists glare and suits industrial aesthetics\u003c\/li\u003e\n\u003cli\u003eLightweight construction at 1 pound per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/2-13 threaded shafts, studs, or inserts commonly found in industrial machinery, equipment panels, jigs, and fixtures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no special tools — thread the knob onto a compatible 1\/2-13 shaft or stud by hand. Ensure the mating thread is clean and free of debris before installation to avoid cross-threading. Verify that thread engagement length is sufficient for the load and application before putting the assembly into service. Do not apply power tools to this knob, as overtightening may damage the thermoplastic hub or strip the mating thread.\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: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Thermoplastic Elastomer overmold, Polypropylene inner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.29 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Height\u003c\/strong\u003e: 0.57 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Matte\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: 1 pound\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: KN8C1500F7S--21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51722874618162,"sku":"KN8C1500F7S--21","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3a2ab03fda60378919e0bbfa83f13bb6.jpg?v=1788597211","url":"https:\/\/voomisupply.com\/products\/gibraltar-kn8c1500f7s-21-lobed-knob-8-point-black","provider":"Voomi Supply","version":"1.0","type":"link"}
