Made from Grade 8 steel with a yellow zinc dichromate finish, this nut provides strong corrosion resistance alongside the high tensile strength required for demanding fastening work. The nylon insert creates interference with the mating threads, resisting loosening without damaging the bolt or stud. At 1-11\/64 inches in height and 1-5\/8 inches across flats, it is sized for 1-1\/8-7 UNC thread applications. Licensed trades and maintenance professionals working with structural assemblies, heavy equipment, or industrial installations will find this nut suitable for critical fastening points.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is intended for use in applications where thread loosening from vibration or dynamic loading is a concern. The 1-1\/8-7 UNC thread size and Grade 8 steel construction make it appropriate for heavy-duty mechanical assemblies across industrial, construction, and equipment maintenance settings. Right-hand thread direction follows standard convention for most fastening applications. Sold individually, it is suited for single-point replacements or low-quantity service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists vibration-induced loosening without thread damage\u003c\/li\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eYellow zinc dichromate finish offers corrosion protection in exposed or mildly harsh environments\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-7 UNC thread size with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003e1-11\/64 inch height and 1-5\/8 inch width across flats for standard wrench fitment\u003c\/li\u003e\n  \u003cli\u003eInch measurement system, UNC fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for assemblies requiring a 1-1\/8-7 UNC right-hand thread hex lock nut in Grade 8 steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician familiar with fastener torque requirements for the specific assembly. De-energize, de-pressurize, or otherwise make safe any equipment before replacing fasteners in load-bearing or pressurized assemblies. Use a properly sized open-end or box wrench matched to the 1-5\/8 inch across-flats dimension. Nylon insert lock nuts are generally considered single-use fasteners and should not be reused once removed from a torqued application.\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: 1-1\/8-7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: 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\u003eFinish\u003c\/strong\u003e: Yellow Zinc Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-11\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.41 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: R52001584\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693412909362,"sku":"R52001584","price":18.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a21ccdff3a81ed8a7e926652613d066_17c37b1e-9b7f-4435-82f5-413d58559f55.jpg?v=1788312025","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001584-hex-lock-nut-1-1-8-7-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
