Built to Grade 8 steel with a zinc yellow dichromate finish, this nut delivers high tensile strength and corrosion resistance in demanding mechanical environments. The 1-1\/8-12 UNF thread specification makes it suitable for fine-pitch applications where precise thread engagement and controlled preload are required. It measures 1-11\/64 inches in height and 1-5\/8 inches across the flats, fitting standard hex tooling. Mechanical contractors, millwrights, and equipment technicians install this type of fastener in structural, drivetrain, and industrial assemblies.\u003c\/p\u003e\n\u003cp\u003eThis nylon insert lock nut is used in residential and commercial mechanical applications where vibration-resistant fastening is critical. Common install scenarios include equipment mounts, HVAC framework, pump housings, and structural brackets requiring a fine-thread UNF fastener. The right-hand thread direction is standard for the vast majority of mechanical assemblies. It is sold individually and is appropriate wherever a single high-strength, self-locking hex nut in the 1-1\/8-12 thread size is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking mechanism resists loosening from vibration and dynamic loads\u003c\/li\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion resistance in exposed or mildly harsh environments\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-12 UNF fine-pitch thread for precise engagement and controlled preload\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard tooling and fastener systems\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with UNSPSC classification 31161716 for procurement accuracy\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 mechanical assemblies requiring a 1-1\/8-12 UNF Grade 8 nylon insert hex lock nut with a zinc yellow dichromate finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or trades professional using a properly sized hex wrench or socket matching the 1-5\/8-inch across-flats dimension. De-energize and isolate any equipment before servicing fastened assemblies. Nylon insert lock nuts are intended for single-use applications — once the nylon locking element has been compressed, reuse may reduce locking effectiveness. Follow applicable mechanical codes and equipment manufacturer torque specifications when tightening.\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\/8-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF\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: Grade 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: 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\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\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\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: R52001583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699689947442,"sku":"R52001583","price":17.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65a8912e052c7fc27df8ce5ad0462596.jpg?v=1788379251","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001583-hex-lock-nut-1-1-8-12-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
