The nylon insert creates prevailing torque that resists loosening caused by vibration and dynamic loading, making this nut a reliable choice for structural and mechanical fastening applications. At 63\/64 inches in height and 1-1\/4 inches across the flats, this nut meets standard dimensional requirements for 7\/8-9 threaded assemblies. Installation and removal require a right-hand thread direction. Licensed tradespeople and industrial maintenance technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is suited for heavy-duty mechanical assemblies where vibration resistance is critical. Typical applications include structural steel connections, heavy equipment frames, agricultural machinery, and industrial fabrication. The Grade 8 steel construction is appropriate for high-strength fastening requirements. The yellow zinc dichromate finish provides a degree of corrosion resistance for indoor and moderately exposed environments. This nut is sold individually with a minimum order quantity of 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style prevents loosening under vibration and dynamic loads\u003c\/li\u003e\n\u003cli\u003eGrade 8 steel construction for high-strength fastening applications\u003c\/li\u003e\n\u003cli\u003eYellow zinc dichromate finish offers corrosion resistance\u003c\/li\u003e\n\u003cli\u003e7\/8-9 UNC thread size with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003eStandard hex profile accepts common 1-1\/4 inch across-flats wrenching tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or assembly nut for 7\/8-9 UNC right-hand threaded bolts and studs used in high-strength fastening applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician familiar with fastener torque requirements for Grade 8 hardware. Always ensure the mating bolt or stud is free of debris and properly lubricated per the assembly specification before threading the nut. Do not exceed the rated clamp load for the fastener grade. Replace any nut that shows signs of damaged threads or a deformed nylon insert, as locking effectiveness will be compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 7\/8-9\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\u003eHeight\u003c\/strong\u003e: 63\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Yellow Zinc Dichromate\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: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: R52001595\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695020114226,"sku":"R52001595","price":62.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/251bae12084609a495e8c4ea45d1a98b.jpg?v=1788330592","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001595-hex-lock-nut-7-8-9-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
