The nylon insert deforms around the mating thread under torque, creating prevailing-torque resistance that keeps the nut from backing off under vibration or dynamic loading. At 39\/64 inches high with a 3\/4-inch across-flats dimension, this fastener fits standard 1\/2-inch drive and wrench tooling. Plumbers, electricians, HVAC technicians, and general mechanical trades use this style of lock nut wherever a reliable, reusable locking fastener is required on inch-series threaded assemblies.\u003c\/p\u003e\n\u003cp\u003eThis nylon insert hex lock nut is suited for light to medium-duty mechanical assemblies in residential and commercial applications. Common use cases include equipment mounting, panel fastening, pipe hanger assemblies, and any joint subject to vibration where a standard nut would loosen over time. The right-hand thread direction is compatible with the vast majority of standard inch-series fastener applications. Minimum order quantity for this SKU is 50 pieces, sold as single units per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert provides prevailing-torque locking without adhesives or separate locking hardware\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF thread for fine-pitch engagement and improved clamp load retention\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance in indoor and sheltered environments\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction matches standard inch-series fastener tooling\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch across flats accepts standard 3\/4-inch open-end, box, or socket wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2-20 UNF male-threaded fasteners following inch-series standards.

Nylon insert lock nuts are designed for use on clean, undamaged threads — inspect mating bolts or studs before assembly. The nylon insert is rated for a limited number of reuse cycles; replace the nut if the locking torque feels significantly reduced on reinstallation. Ensure the joint is de-energized or depressurized as appropriate to the system before performing any fastener service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20 UNF\u003c\/li\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 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: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 39\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF Inch Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R50000017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721481027890,"sku":"R50000017","price":1659.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a477cacaad6c39449d4b8fd71ef1fcc2.jpg?v=1788577915","url":"https:\/\/voomisupply.com\/products\/value-collection-r50000017-hex-lock-nut-1-2-20-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
