Designed for hand-tightening applications, this knob allows tool-free adjustments on fixtures, jigs, machine guards, and industrial equipment. The nylon construction keeps the knob lightweight and resistant to corrosion, making it suitable for both shop and light industrial environments. The female insert accepts a 5\/16-18 UNC threaded fastener, providing a secure, reliable connection point wherever repeated manual adjustment is needed.\u003c\/p\u003e\n\u003cp\u003eThis fluted knob is used in manufacturing, maintenance, and assembly applications where operators need to make frequent adjustments without reaching for a wrench. Common installation scenarios include clamping assemblies, panel fastening, equipment guards, and workholding fixtures. Machinists, maintenance technicians, and industrial assembly workers are the primary installers. The fluted grip profile improves torque transfer by hand, especially in confined spaces or gloved-hand conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5-inch head diameter for comfortable hand grip and increased manual torque\u003c\/li\u003e\n  \u003cli\u003eNylon construction — lightweight, corrosion resistant, and electrically non-conductive\u003c\/li\u003e\n  \u003cli\u003eFemale threaded insert sized for 5\/16-18 UNC fasteners\u003c\/li\u003e\n  \u003cli\u003eFluted outer profile improves grip in bare-hand and light-glove use\u003c\/li\u003e\n  \u003cli\u003eTool-free installation and adjustment for high-cycle access panels and fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or new-installation fluted knob for any threaded stud or bolt with a 5\/16-18 UNC thread pattern on industrial equipment, fixtures, and machine guards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis knob is installed by threading it onto an existing 5\/16-18 UNC stud or bolt by hand. No special tools are required for installation. Ensure the mating thread is clean and free of debris before engaging the insert to avoid cross-threading the nylon. Do not use a wrench or driver on the knob body, as excessive torque can crack the nylon or strip the insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Female threaded insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.465 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: G10-4300FC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51690209411378,"sku":"G10-4300FC","price":40.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a764659fd6b7c9029277114916e65ceb.jpg?v=1788267358","url":"https:\/\/voomisupply.com\/products\/gibraltar-g10-4300fc-fluted-knob-2-5-in-nylon-female-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
