The nylon insert creates friction against the mating thread to resist loosening from vibration and torque without requiring a secondary locking component. At 23\/64 inches high with a 1\/2-inch width across flats, this nut suits high-strength fastening applications where a standard hex nut would be insufficient. It follows UNC thread standards with a right-hand thread direction and weighs approximately 0.011 pounds per unit. Installation requires a standard open-end or box wrench sized for a 1\/2-inch hex.\u003c\/p\u003e\n\u003cp\u003eThis nylon insert lock nut is suited for mechanical assemblies, structural connections, and equipment maintenance tasks where vibration resistance is a priority. Grade 8 steel construction makes it appropriate for high-load environments in industrial, agricultural, and heavy equipment settings. The zinc yellow dichromate finish provides corrosion resistance for moderate-exposure applications. It is commonly installed by millwrights, maintenance technicians, and mechanical contractors working on steel fabrications and equipment frames.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening under vibration without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance in moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003eUNC 5\/16-18 thread size with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003e23\/64 inches height and 1\/2-inch width across flats for standard wrench compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/16-18 UNC right-hand threaded fasteners and bolts in Grade 8 or compatible steel assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand-threading the nut onto the mating bolt until snug, then tightening with an open-end or box wrench sized to 1\/2-inch across flats. De-energize or lock out any equipment before performing fastener replacement or tightening in powered machinery per applicable OSHA lockout\/tagout procedures. Do not reuse nylon insert lock nuts that have been fully torqued, as the nylon insert loses clamping effectiveness after initial compression.\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\u003eLocking Style\u003c\/strong\u003e: Nylon 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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eInsert Material\u003c\/strong\u003e: Nylon\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\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 39652\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717401936178,"sku":"39652","price":2657.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/612777ccc504c49282db03ef99e747aa.jpg?v=1788539789","url":"https:\/\/voomisupply.com\/products\/value-collection-39652-hex-lock-nut-5-16-18-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
