It is manufactured from Grade 8 steel and left uncoated, making it suitable for high-strength fastening applications where vibration resistance is required. The nylon insert deforms around the mating thread to create a prevailing torque that resists loosening without the need for additional locking hardware. At 63\/64 inches in height with a 1-1\/4 inch width across flats, this nut conforms to UNC thread standards with a right-hand thread direction. Trade professionals, maintenance crews, and mechanical contractors rely on this type of fastener in structural and equipment assembly work.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is used in mechanical, structural, and industrial assembly applications where a secure, vibration-resistant threaded connection is required. It is appropriate for use in heavy equipment, HVAC curb mounting, structural steel connections, and similar applications that demand Grade 8 fastener strength. The UNC thread form and inch measurement system make it compatible with standard American fastener tooling and hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style resists loosening under vibration without additional locking hardware\u003c\/li\u003e\n\u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003e7\/8-9 UNC thread size with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for applications where coating is applied after assembly or not required\u003c\/li\u003e\n\u003cli\u003e63\/64 inch height and 1-1\/4 inch width across flats for standard wrench fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC inch-series hex lock nut for use with 7\/8-9 threaded fasteners and hardware in structural and mechanical assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical or maintenance personnel using a properly sized wrench or socket matched to the 1-1\/4 inch width across flats. Verify mating bolt grade and thread engagement depth are appropriate for the load requirements before final torquing. De-energize or lock out any equipment before servicing fastened assemblies on powered systems. The nylon insert is single-use and should not be reinstalled once removed, as the locking torque will be reduced.\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\/8-9\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: Grade 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: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 63\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/4 inches\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\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: MP39629\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720432550194,"sku":"MP39629","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/038a5a3a48827f144d0cb31e93078ff8.jpg?v=1788563856","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39629-hex-lock-nut-7-8-9-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
