The nylon insert deforms around the bolt threads to create friction-based prevailing torque, resisting loosening caused by vibration and dynamic loads without requiring a separate lock washer or adhesive. Constructed from Grade 2 steel with a zinc-plated finish, this nut stands 1-9\/32 inches high and measures 1-5\/8 inches across the flats. It is sized for heavy-duty mechanical, structural, and industrial assembly work where a standard hex nut does not provide adequate locking force.\u003c\/p\u003e\n\u003cp\u003eThis nut is suited for general industrial, commercial, and trade applications involving 1-8 UNC coarse-thread fasteners. Common install scenarios include equipment mounting, pipe support hardware, mechanical frames, HVAC structural components, and electrical enclosure assemblies. The right-hand thread direction is standard for conventional fastening. Sold individually, it is appropriate for repair, replacement, or single-point assembly needs across maintenance and construction trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert provides prevailing torque locking without adhesives or secondary locking hardware\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC coarse thread for broad fastener compatibility in heavy-duty applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose structural strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance in indoor and sheltered environments\u003c\/li\u003e\n  \u003cli\u003eHeavy hex profile with 1-5\/8 inch across-flats for high-torque wrench engagement\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction follows standard fastening convention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1-8 UNC coarse-thread bolts and studs.

De-energize or depressurize any system before servicing fastened components. Nylon insert lock nuts are generally intended for single use — once removed, the nylon insert may not provide the same prevailing torque on reinstallation and replacement is recommended. Follow applicable mechanical or structural codes for torque sequencing on critical joints.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Heavy Hex Lock Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8\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\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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-9\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-5\/8 inches (1.6020 to 1.6320 inches decimal range)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 1.7960 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: B52001663\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692569657650,"sku":"B52001663","price":17.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7b1625e7e6688e16297e3ae573a0897.jpg?v=1788299484","url":"https:\/\/voomisupply.com\/products\/value-collection-b52001663-heavy-hex-lock-nut-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
