Manufactured from Grade 8 steel with a bright, uncoated finish, this nut uses a nylon insert locking mechanism to maintain clamp load under dynamic loads and vibration without the need for thread-locking compounds. It is sized to a 1-1\/4-12 UNF thread and measures 1-25\/64 inches in height with a 1-13\/16 inch width across flats. Electricians, millwrights, and maintenance mechanics install this type of hardware in mechanical assemblies, structural connections, and equipment mounting applications where a secure, reusable fastening solution is required.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is suited for industrial, commercial, and heavy-duty mechanical installations where a fine-thread, right-hand UNF fastener is specified. The 1-1\/4-12 thread pitch is common in precision mechanical assemblies, hydraulic fittings, and structural steel applications where greater thread engagement and load distribution are priorities. It is sold individually and is appropriate for shops and field technicians carrying Grade 8 fastener inventory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style provides vibration-resistant clamping without thread-locking compounds\u003c\/li\u003e\n\u003cli\u003eGrade 8 steel construction delivers high tensile and proof load capacity\u003c\/li\u003e\n\u003cli\u003e1-1\/4-12 UNF fine thread for precise engagement and increased clamping force\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction conforms to standard installation practices\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for indoor and protected-environment use\u003c\/li\u003e\n\u003cli\u003eInch measurement system; conforms to UNF fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNF replacement or service fastener for applications requiring a 1-1\/4-12 Grade 8 nylon insert hex lock nut.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician using the appropriate size wrench or socket matched to the 1-13\/16 inch width across flats. Ensure mating threads are clean, undamaged, and free of debris before installation. Nylon insert lock nuts are intended for single-use or limited-reuse service; replace the nut if the nylon insert no longer provides resistance during installation. Do not exceed the torque ratings specified by the equipment manufacturer or applicable fastener standards for Grade 8 UNF hardware.\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: 1-1\/4-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF\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: 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\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\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\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: MP39646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698952274226,"sku":"MP39646","price":33.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e3e17732366fc84acc327b930869e66.jpg?v=1788370288","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39646-hex-lock-nut-1-1-4-12-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
