It uses a nylon collar at the top of the nut that deforms around mating threads to create a prevailing-torque locking action without requiring adhesive or additional hardware. Manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance, it carries a 1-1\/8-12 UNF right-hand thread and measures 41\/64 inches in height with a 1-5\/8-inch width across flats. It is sold individually with a minimum order quantity of 5 units.\u003c\/p\u003e\u003cp\u003eThis nut is suited for general mechanical assembly applications where vibration resistance is required and reuse is acceptable. Common install scenarios include structural fastening, equipment mounting, and machinery assembly in industrial, commercial, and trade service environments. The UNF thread designation indicates a fine-pitch profile, which provides higher thread engagement per inch and is common in applications requiring precise axial adjustment or where higher clamping force is needed in limited engagement lengths.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style provides prevailing-torque resistance without adhesives or secondary locking hardware\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction suitable for general-purpose fastening applications\u003c\/li\u003e\n\u003cli\u003eZinc finish offers basic surface protection against corrosion\u003c\/li\u003e\n\u003cli\u003e1-1\/8-12 UNF fine-pitch right-hand thread for precise thread engagement\u003c\/li\u003e\n\u003cli\u003e41\/64 inch height and 1-5\/8 inch width across flats for standard hex tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose UNF hex lock nut compatible with 1-1\/8-12 right-hand threaded fastener assemblies requiring a nylon insert prevailing-torque locking element.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a mechanic or maintenance technician using a standard open-end or combination wrench sized to the 1-5\/8 inch across-flats dimension. Ensure mating bolt threads are clean and free of damage before installation. Because the nylon insert creates drag during installation, a torque wrench is recommended to avoid overtightening. Note that each reuse of a nylon insert nut reduces the prevailing-torque locking effectiveness; replace the nut if the nylon insert shows visible wear or deformation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/8-12\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\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\u003eInsert Material\u003c\/strong\u003e: Nylon\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 41\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 305484PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700175601970,"sku":"305484PS","price":79.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf8559402d0ee881c2f2f233f80b049a.jpg?v=1788387186","url":"https:\/\/voomisupply.com\/products\/value-collection-305484ps-hex-lock-nut-1-1-8-12-nylon-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
