Manufactured from Grade C steel with a zinc-plated and waxed finish, this nut provides corrosion resistance and consistent torque performance on installation. The right-hand thread follows standard UNF inch-series fastener specifications. It is sold in a package of 50 and is suited for general mechanical assembly and maintenance applications across HVAC, plumbing, electrical, and industrial trades.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is used in residential and commercial mechanical installations wherever a reliable, reusable thread-locking fastener is required on 1\/2-20 UNF threaded fasteners. Distorted thread nuts are commonly applied in vibration-prone environments such as equipment mounting, fan assemblies, motor brackets, and structural panel connections. The zinc-and-wax finish supports installation in mildly corrosive or outdoor-adjacent environments. Tradespeople working on HVAC equipment frames, electrical enclosures, and plumbing supports will find this a standard consumable for field and shop work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDistorted thread locking style resists loosening under vibration without secondary locking components\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF right-hand thread per inch-series fastener standards\u003c\/li\u003e\n  \u003cli\u003eGrade C steel construction for reliable mechanical strength in general-duty applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated with wax finish for corrosion resistance and consistent installation torque\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 50 to support multi-unit jobs and shop stock\u003c\/li\u003e\n  \u003cli\u003eDoes not meet military specifications — appropriate for commercial and trade applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF inch-series hex lock nut for use with any 1\/2-20 right-hand threaded fastener in general mechanical, HVAC, electrical, and plumbing assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench or socket set sized for 1\/2-inch fasteners. Ensure mating threads are clean and free of debris before installation to maintain the distorted thread locking engagement. Do not reuse distorted thread lock nuts in critical load-bearing applications after removal, as repeated cycling reduces the locking effectiveness. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Distorted Thread\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated with Wax\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KP66145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699241779506,"sku":"KP66145","price":50.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce818f431a40ec4b615b1004ad820bb4.jpg?v=1788374023","url":"https:\/\/voomisupply.com\/products\/value-collection-kp66145-hex-lock-nut-1-2-20-unf-grade-c-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
