The nylon insert creates interference with the mating thread to resist loosening from vibration and torque loads without damaging the fastener thread. At 1-25\/64 inches in height and 1-13\/16 inches across the flats, this nut is sized for heavy-duty structural and mechanical fastening applications. Right-hand thread direction follows standard UNC conventions. Machinists, millwrights, maintenance mechanics, and general contractors use this fastener in equipment assembly, structural connections, and machinery where reliable prevailing-torque locking is required.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for industrial, commercial, and heavy equipment applications where Grade 8 steel strength and reliable vibration resistance are required. It is appropriate for use in static and dynamic load environments including machinery frames, structural steel connections, and mechanical assemblies using 1-1\/4-7 UNC threaded fasteners. The bright uncoated finish is standard for indoor and protected installations where corrosion exposure is minimal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style provides prevailing-torque resistance without damaging mating threads\u003c\/li\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-7 UNC thread size with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eHeight of 1-25\/64 inches and width across flats of 1-13\/16 inches for standard hex wrench fitment\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for protected or indoor service environments\u003c\/li\u003e\n  \u003cli\u003eConforms to inch measurement system under UNC fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any 1-1\/4-7 UNC Grade 8 or compatible threaded bolt or stud in standard inch-system mechanical and structural assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand and with a standard hex wrench or impact tool sized for a 1-13\/16-inch across-flats hex nut. De-energize or lock out any machinery before servicing fastened assemblies per applicable OSHA lockout\/tagout procedures. Nylon insert lock nuts are generally considered single-use; replace the nut if the nylon insert shows deformation or if the prevailing torque feel is reduced upon reuse. Do not exceed the rated torque range for Grade 8 fasteners of this thread size.\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\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7\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\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: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-25\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: MP39632\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722874487090,"sku":"MP39632","price":39.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/281b5558a6b929fa95a486df21398518.jpg?v=1788597208","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39632-hex-lock-nut-1-1-4-7-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
