The nylon insert collar deforms around mating threads under torque, creating friction-based resistance to loosening caused by vibration or thermal cycling. At 0.3125 inches high with a 0.75-inch across-flats dimension, this fastener suits standard hex tooling and fits flush in most hex pocket applications. Plumbers, HVAC technicians, electricians, and general trade contractors use nylon insert lock nuts wherever stainless corrosion resistance is required alongside reliable thread retention.\u003c\/p\u003e\u003cp\u003eThis lock nut is suited for use in corrosive or moisture-prone environments where carbon steel fasteners would oxidize and seize. Typical applications include mechanical equipment assemblies, pipe support hardware, electrical enclosure mounting, HVAC equipment frames, and structural fastening in coastal or chemical-exposure settings. The 18-8 stainless alloy provides solid resistance to rust and mild chemical exposure without the added cost of 316-grade material. Right-hand thread direction matches the overwhelming majority of standard inch-series fastener applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking collar resists vibration-induced loosening without adhesive or secondary locking hardware\u003c\/li\u003e\n\u003cli\u003eGrade 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread size for compatibility with standard inch-series bolts and threaded rod\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish maintains dimensional tolerances and is suitable for contact with stainless hardware\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction conforms to standard UNC fastener practice\u003c\/li\u003e\n\u003cli\u003eWidth across flats of 0.75 inches accepts standard 3\/4-inch hex wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC 1\/2-13 inch-series hex lock nut for use with any matching 1\/2-13 threaded bolt, stud, or threaded rod requiring a nylon insert locking nut.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/4-inch hex wrench or socket. Apply fastener torque in accordance with the equipment manufacturer specifications and applicable mechanical codes. Do not reuse a nylon insert lock nut after removal, as the nylon collar loses its locking effectiveness once fully engaged and backed off. Ensure mating threads are clean and free of debris before installation to achieve full thread engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut with Nylon Insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 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: 18-8 Stainless Steel\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: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.741 to 0.752 inches (nominal 0.75 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 0.837 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 1-THN-50C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694891565362,"sku":"1-THN-50C","price":1665.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34aea92b8e32e9219dd15d2eedf5c0f3.jpg?v=1788329401","url":"https:\/\/voomisupply.com\/products\/value-collection-1-thn-50c-hex-lock-nut-1-2-13-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
