Threaded at 7\/16-20 with a right-hand thread direction, it meets the demands of high-strength bolted assemblies found in HVAC equipment mounting, plumbing support structures, and general mechanical installations. The cadmium waxed finish provides corrosion resistance and serves as a dry-film lubricant to assist with consistent torque application during installation. At 0.375 inches high with a width across flats of 0.6875 inches, this nut fits standard 7\/16-20 hex tooling. Licensed tradespeople and mechanical contractors working on structural and equipment fastening applications specify this nut where Grade 9 strength ratings are required.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for high-vibration mechanical assemblies in residential and commercial trade applications. Typical install scenarios include equipment base frames, pipe hanger hardware, bracket mounting, and other structural connections that require a secure, torque-resistant fastener. The 7\/16-20 fine thread pitch provides higher thread engagement per inch compared to coarse thread, making it appropriate where precise clamping force and resistance to loosening are priorities. Sold in packages of 50, it is practical for service vehicles and shop stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 steel construction for high-strength fastening in demanding mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 fine right-hand thread for consistent torque and secure engagement\u003c\/li\u003e\n  \u003cli\u003eCadmium waxed finish provides corrosion resistance and lubrication during installation\u003c\/li\u003e\n  \u003cli\u003e0.375 inches height and 0.6875 inches width across flats for standard hex tooling compatibility\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 50 units suitable for shop stock or field inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service stock hex lock nut for 7\/16-20 threaded fastener applications requiring Grade 9 steel strength ratings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed mechanical contractors, HVAC technicians, plumbers, or qualified tradespeople using standard hex wrenches or sockets sized to 0.6875 inches across flats. De-energize or depressurize the associated system before servicing any fastened assembly. Verify thread engagement and confirm the mating bolt or stud is also rated for the load requirements of the assembly. Do not mix Grade 9 nuts with lower-grade fastener hardware in high-load applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Cadmium Waxed\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: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161716\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: BOWMALLOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36798\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51998179950898,"sku":"36798","price":103.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bde0ce8aee8df64c99596e79e5a8ad3_3eaf09d1-c147-493c-923c-c092deb6bec5.jpg?v=1789994698","url":"https:\/\/voomisupply.com\/products\/bowmalloy-36798-hex-lock-nut-7-16-20-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
