Designed for hand-tightening applications where tools are not practical or permitted, this knob provides a comfortable, slip-resistant grip across its 1.91-inch head diameter. The 5\/16-18 threaded stem with a 1-inch thread length allows direct mounting to compatible threaded shafts, studs, or inserts. At 0.1 pounds, it is a lightweight hardware component suited for panel assemblies, enclosures, access covers, and equipment requiring frequent manual adjustment. Licensed tradespeople and equipment assemblers install this type of fastening knob across HVAC, electrical, and general industrial applications.\u003c\/p\u003e\u003cp\u003eThis lobed knob is used wherever a secure, tool-free hand grip is needed on threaded fasteners. Typical applications include control panel doors, filter access covers, junction box lids, and equipment mounting fixtures in both residential and commercial settings. The TPE construction resists oils, mild chemicals, and repeated handling without degrading grip quality. It is suited for light to moderate clamping loads where finger-tightening torque is sufficient for the assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-point lobed profile provides multi-finger grip and consistent hand torque\u003c\/li\u003e\n\u003cli\u003eThermoplastic elastomer construction offers oil resistance and a non-slip surface\u003c\/li\u003e\n\u003cli\u003e1.91-inch head diameter delivers adequate leverage for hand tightening\u003c\/li\u003e\n\u003cli\u003e5\/16-18 threaded stem with 1-inch thread length for broad fastener compatibility\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.1 pounds — suitable for weight-sensitive panel and enclosure assemblies\u003c\/li\u003e\n\u003cli\u003eBlack finish for low-visibility integration into equipment housings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-thread replacement or upgrade knob for any application using a 5\/16-18 threaded shaft, stud, or insert requiring hand-tightening access.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no special tools — thread the knob onto a compatible 5\/16-18 stud or shaft by hand. Ensure the mating thread is clean and free of debris before installation. Do not use power tools to drive or remove this knob, as TPE components are not rated for high-torque power driving. Verify that finger-tightening torque is sufficient for the clamping load required by the assembly before use.\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: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Thermoplastic Elastomer (TPE)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.91 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 0.93 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Height\u003c\/strong\u003e: 0.17 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.09 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 5B50B931A8Z002G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51722370220338,"sku":"5B50B931A8Z002G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d13bf3dc886bc9f95b4313113aa659b.jpg?v=1788590154","url":"https:\/\/voomisupply.com\/products\/gibraltar-5b50b931a8z002g-lobed-knob-5-point-black","provider":"Voomi Supply","version":"1.0","type":"link"}
