The nylon insert collar deforms around the mating thread when driven, creating a friction-based locking action without the need for adhesives or secondary locking hardware. The zinc plated steel construction provides corrosion resistance suitable for general indoor and light-duty outdoor applications. Sold in a 50-piece pack, this nut is a standard fastener used across HVAC equipment assembly, plumbing rough-in work, electrical enclosure mounting, and mechanical installations where thread retention is required.\u003c\/p\u003e\n\u003cp\u003eThis lock nut is appropriate for residential and light commercial applications wherever a 1\/2-13 UNC threaded fastener connection requires vibration resistance. Common install scenarios include equipment brackets, fan motor mounts, pipe support strut systems, and structural fastening in mechanical rooms. The 50-piece pack quantity suits service vehicles and job-site replenishment for technicians who regularly work with half-inch hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert collar provides friction-based thread locking without adhesives\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 coarse thread (UNC) for broad compatibility with standard hardware\u003c\/li\u003e\n  \u003cli\u003eZinc plated steel construction for corrosion resistance in general service environments\u003c\/li\u003e\n  \u003cli\u003e50-piece pack quantity for job-site or service truck stocking\u003c\/li\u003e\n  \u003cli\u003eResists loosening from vibration and mechanical shock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock fastener for any application requiring a 1\/2-13 UNC coarse thread nylon insert lock nut in zinc plated steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNylon insert lock nuts are installed by hand-threading onto the mating bolt or stud, then driven to final torque with a wrench or socket following applicable project fastener specifications. Power down or de-energize any equipment before working on fastened assemblies in electrical or HVAC systems. Nylon insert lock nuts are generally intended for single-use service, as the nylon insert loses clamping effectiveness after removal and reinstallation. Follow applicable mechanical or structural codes for torque and fastener grade requirements on the specific installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Coarse (UNC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc Plated Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Type\u003c\/strong\u003e: Nylon Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 26.8 pounds\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: HILLMAN FASTENERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 180159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51559560937778,"sku":"180159","price":196.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/232d5f2ff41b759c77aa6a7fc8d85b43_1b6447bd-92df-41b6-bfa8-3c9f13c17235.jpg?v=1786435290","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-180159-lock-nut-1-2-13-coarse-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
