Built to Grade 8 steel with an uncoated finish, this nut meets UNC thread standards at a 1-1\/2-6 thread size. It measures 1-39\/64 inches in height with a width across flats of 2-3\/16 inches. The right-hand thread and nylon insert combine to resist loosening under load, making this nut a reliable choice for structural, mechanical, and industrial assemblies handled by maintenance mechanics, millwrights, and general trade professionals.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for use in heavy equipment, structural steel assemblies, and industrial machinery where a 1-1\/2-6 UNC Grade 8 fastener is specified. The nylon insert provides prevailing torque resistance without thread damage, making it appropriate for both initial installation and controlled re-use in moderate-duty applications. Uncoated finish is standard for applications where surface treatment is applied separately or not required by the assembly specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening caused by 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\u003e1-1\/2-6 UNC right-hand thread for compatibility with standard inch-series fastener systems\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for secondary treatment or bare-steel assembly requirements\u003c\/li\u003e\n  \u003cli\u003eHeight of 1-39\/64 inches and width across flats of 2-3\/16 inches for standard heavy hex form factor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC inch-series hex lock nut for use with 1-1\/2-6 right-hand threaded bolts and studs in Grade 8 or equivalent high-strength fastener assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by maintenance mechanics, millwrights, or structural ironworkers using appropriately sized box-end wrenches or impact sockets rated for the torque required by the assembly specification. Always de-energize, depressurize, or otherwise isolate the assembly before servicing fasteners on live equipment. The nylon insert provides a prevailing torque fit; do not reuse this nut if the insert shows visible deformation or has been torqued beyond its service limit. Consult the applicable engineering specification or torque table for the correct target value based on bolt grade and diameter.\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\/2-6\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: UNC\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: 1-39\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 2-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Uncoated\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: MP39634\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723156947250,"sku":"MP39634","price":28.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe4427592185111928948fd39ff71568.jpg?v=1788601400","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39634-hex-lock-nut-1-1-2-6-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
