The nylon insert creates interference with the mating thread, resisting loosening caused by vibration and torque. At 23\/64 inches high with a 1\/2-inch width across flats, this nut is sized for standard 5\/16-inch fastener applications. The zinc yellow dichromate coating provides a baseline level of corrosion resistance. Installation requires a right-hand thread direction. Sold individually with a minimum order quantity of 100 units.\u003c\/p\u003e\n\u003cp\u003eThis lock nut is suited for mechanical, industrial, and light structural assembly applications where vibration resistance is required on fine-thread fastener systems. The 5\/16-24 UNF thread designation makes it appropriate for precision assemblies, automotive, and equipment manufacturing environments where fine pitch threading is specified. Electricians, millwrights, and general mechanical trades commonly use this nut type when securing components subject to dynamic loads or continuous vibration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening under vibration without damaging mating threads\u003c\/li\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength applications\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNF right-hand thread for fine-pitch fastener systems\u003c\/li\u003e\n  \u003cli\u003eStandard hex profile — 1\/2 inch across flats — fits common wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eHeight of 23\/64 inches for compact installation clearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/16-24 UNF right-hand threaded fasteners in inch-measurement mechanical assemblies requiring a nylon insert hex lock nut.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis nut should be installed by hand until the nylon insert contacts the bolt, then torqued with a standard 1\/2-inch open-end or box wrench. Power down or de-energize any associated equipment before performing fastener service. Nylon insert lock nuts are generally single-use — the insert may lose clamping effectiveness if removed and reinstalled on the same fastener. Follow applicable mechanical or structural codes for torque requirements based on joint design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Style\u003c\/strong\u003e: Nylon Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 23\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R52001683\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698094506290,"sku":"R52001683","price":3874.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64f0e8828ad1f75b1870c645aba57a49.jpg?v=1788357667","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001683-hex-lock-nut-5-16-24-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
