It features a female threaded insert sized for a 5\/16-18 fastener, making it a hand-tightening control component used in light machinery, jigs, fixtures, enclosures, and industrial equipment. The knurled and fluted outer profile provides secure grip without tools. This type of knob is typically installed by maintenance technicians, machine operators, and equipment assemblers working in manufacturing, fabrication, or MRO applications.\u003c\/p\u003e\n\u003cp\u003eThis knob is suited for applications where tool-free hand adjustment is required. Common installations include panel doors, guard covers, fixture clamps, and equipment access points. The female insert design accepts a threaded stud or screw, allowing the knob to be threaded directly onto a fixed post or bolt. The plastic construction keeps the assembly lightweight and resistant to corrosion in moderate-duty environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5-inch head diameter for a full hand grip\u003c\/li\u003e\n  \u003cli\u003eKnurled and fluted outer surface for tool-free tightening and loosening\u003c\/li\u003e\n  \u003cli\u003eFemale threaded insert accepts 5\/16-18 fasteners\u003c\/li\u003e\n  \u003cli\u003ePlastic construction — lightweight and corrosion resistant\u003c\/li\u003e\n  \u003cli\u003eDesigned for hand-adjustment applications in fixtures, panels, and machinery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct fitment knob for equipment and fixtures using a 5\/16-18 threaded stud or bolt interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools — thread the female insert directly onto a 5\/16-18 stud or cap screw by hand. Verify thread engagement is sufficient before applying load. Do not overtighten, as the plastic body can crack under excessive torque. Ensure the mating stud protrudes enough to engage the full depth of the insert for secure retention.\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: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Style\u003c\/strong\u003e: Knurled Fluted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: G10-2890-A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51693851443506,"sku":"G10-2890-A","price":67.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80f3ed1267b3ca480dfbd9257d5eecd9.jpg?v=1788318199","url":"https:\/\/voomisupply.com\/products\/gibraltar-g10-2890-a-knurled-fluted-knob-2-5-in-plastic","provider":"Voomi Supply","version":"1.0","type":"link"}
