The nylon insert compresses against the mating thread to resist loosening under vibration and torque without the need for adhesives or separate locking washers. At 15\/32 inches high with 11\/16 inches across the flats, this nut follows Unified National Fine (UNF) thread standards with a right-hand thread direction. It is suited for high-strength mechanical assemblies where fastener retention is critical.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is used in industrial, mechanical, and trade applications requiring reliable thread locking in steel assemblies. The Grade 8 material rating makes it appropriate for high-load fastening scenarios in equipment maintenance, structural brackets, and machinery. Technicians and maintenance professionals working with UNF-threaded fastener systems will find this nut compatible with standard 7\/16-20 bolts and studs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style resists loosening from vibration without adhesives\u003c\/li\u003e\n\u003cli\u003eGrade 8 steel construction for high tensile strength applications\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish provides corrosion resistance\u003c\/li\u003e\n\u003cli\u003e7\/16-20 UNF right-hand thread for standard compatibility\u003c\/li\u003e\n\u003cli\u003e15\/32 inch height and 11\/16 inch width across flats for standard hex tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 7\/16-20 UNF threaded bolts and studs in Grade 8 or equivalent high-strength steel fastener assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a standard hex wrench or socket sized to 11\/16 inches across the flats. Power down or de-energize any equipment before accessing fastener locations on mechanical assemblies. The nylon insert is single-use by design and should not be reused after removal, as the locking torque degrades with each installation cycle. Follow applicable mechanical and structural codes for torque requirements based on the specific assembly.\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\/16-20\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: UNF\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\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 15\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: MP39664\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702368370994,"sku":"MP39664","price":32.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecbb0b367eef0f1d164e665f45cf4076.jpg?v=1788410481","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39664-hex-lock-nut-7-16-20-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
