The nylon insert grips the mating thread and resists loosening under vibration, thermal cycling, and dynamic loading. At 29\/64 inches in height and 5\/8 inches across the flats, this nut fits standard 7\/16-14 fastener assemblies. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, making it a reliable choice in wet, chemical, or marine environments. Right-hand thread direction follows standard UNC convention. Each package contains 25 nuts.\u003c\/p\u003e\u003cp\u003eThese hex lock nuts are suited for plumbing, HVAC, marine, and industrial applications where moisture, salt spray, or chemical exposure is a concern. The nylon insert style is common in equipment assemblies, pipe supports, conduit mounting, and mechanical connections that experience vibration or frequent thermal changes. Installers in commercial and residential mechanical trades use this fastener type when a positive locking solution is required without thread-locking compounds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style resists loosening under vibration and thermal cycling\u003c\/li\u003e\n\u003cli\u003eGrade 316 stainless steel construction for corrosion resistance in harsh or wet environments\u003c\/li\u003e\n\u003cli\u003e7\/16-14 UNC thread size with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003eHeight of 29\/64 inches and 5\/8 inches across the flats for standard wrench fitment\u003c\/li\u003e\n\u003cli\u003eSold in a package of 25 nuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC replacement or new-installation hex lock nut for any 7\/16-14 threaded fastener application requiring a nylon insert locking style.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a standard open-end or combination wrench sized to 5\/8 inches across the flats. De-energize or depressurize any system before replacing fasteners in live assemblies. Nylon insert lock nuts are generally intended for single-use applications; inspect the nylon insert before reuse, as repeated cycling can reduce locking torque. Follow applicable mechanical and structural codes for the specific trade application.\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\/16-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNC\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: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316\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: 29\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\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: 30637\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720147108146,"sku":"30637","price":80.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f73aa96a020c4e6e79f001f90f14ec4f.jpg?v=1788561079","url":"https:\/\/voomisupply.com\/products\/value-collection-30637-hex-lock-nut-7-16-14-316-ss-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
