Built to Grade 8 steel specifications, this nut delivers reliable clamping force in demanding mechanical assemblies. The nylon insert creates interference with the thread flanks, resisting loosening under dynamic loads without damaging the mating fastener. It carries a zinc yellow dichromate finish that provides corrosion resistance in general industrial and mechanical environments. The thread specification is 1-3\/8-12 UNF, right-hand thread, making it compatible with fine-thread fastener systems. Maintenance technicians, mechanical assemblers, and industrial equipment technicians are the primary installers of this fastener.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for use in heavy equipment, industrial machinery, agricultural equipment, and structural assemblies that call for a 1-3\/8-12 UNF fine-thread fastener with positive locking capability. The Grade 8 steel construction supports high clamp loads, and the nylon insert style allows for repeated disassembly and reassembly while maintaining effective locking action. Applications span drive shafts, suspension components, and any assembly subject to vibration or cyclic loading where thread loosening is a failure concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction supports high tensile and proof load requirements\u003c\/li\u003e\n  \u003cli\u003eNylon insert locking style resists vibration-induced loosening without damaging bolt threads\u003c\/li\u003e\n  \u003cli\u003e1-3\/8-12 UNF right-hand thread for compatibility with fine-thread fastener systems\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance in general industrial use\u003c\/li\u003e\n  \u003cli\u003eHeight of 1-37\/64 inches and width across flats of 2 inches for standard wrench fit\u003c\/li\u003e\n  \u003cli\u003eSold individually, suitable for single-unit replacement or low-volume assembly work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance fastener for any assembly requiring a 1-3\/8-12 UNF Grade 8 nylon insert hex lock nut with a 2-inch width across flats.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or assembler familiar with high-strength fastener procedures. Torque the nut with a properly rated wrench to the specification called out in the equipment service manual for Grade 8 fasteners of this thread size. Ensure mating threads are clean and free of debris before installation. The nylon insert is a single-use locking element by design; replace the nut if it has been fully run down and removed, as repeated cycling reduces insert effectiveness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/8-12 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\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\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\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-37\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.77 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161716\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: B52001631\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699522896178,"sku":"B52001631","price":32.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/233e024ee336c09ef5c28fba8fc38394.jpg?v=1788376917","url":"https:\/\/voomisupply.com\/products\/value-collection-b52001631-hex-lock-nut-1-3-8-12-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
