The nut is manufactured from Grade C steel with a zinc-plated and waxed finish that provides corrosion resistance and reduces installation torque. The distorted-thread design deforms slightly as the nut is driven onto a mating fastener, creating mechanical interference that prevents back-off without the need for a separate locking insert or adhesive. This type of hardware is installed by electricians, HVAC technicians, pipefitters, and general maintenance trades wherever a reliable, reusable locking fastener is required in threaded assemblies.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for use in light to medium-duty threaded fastener applications across residential and commercial mechanical, electrical, and HVAC installations. The right-hand thread direction and UNF thread form make it compatible with standard inch-series fastener assemblies. Sold in a 50-piece package, KP66144 is appropriate for stocking in service vehicles, shop bins, or maintenance facilities where 7\/16-20 hardware is used regularly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDistorted-thread locking style resists loosening without adhesives or separate inserts\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 UNF right-hand thread for compatibility with standard inch-series fastener systems\u003c\/li\u003e\n  \u003cli\u003eGrade C steel construction for adequate strength in light to medium-duty applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated with wax finish provides corrosion resistance and eases installation\u003c\/li\u003e\n  \u003cli\u003eSold in a 50-piece package for efficient stocking and bulk service use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stocking hex lock nut for any threaded assembly using a 7\/16-20 UNF inch-series fastener with a right-hand thread direction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard hex wrench or socket sized for a 7\/16-20 nut. De-energize and isolate any electrical or mechanical system before servicing fasteners on live assemblies. Distorted-thread lock nuts are generally reusable for a limited number of cycles; inspect thread condition on reuse. Follow applicable code requirements, including NEC or IFGC where fastener integrity is part of a listed 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\u003eThread Size\u003c\/strong\u003e: 7\/16-20\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\u003eLocking Style\u003c\/strong\u003e: Distorted Thread\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 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: KP66144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717374902578,"sku":"KP66144","price":21.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbbbe3cdb6b95a68167227f73866ca2c.jpg?v=1788539356","url":"https:\/\/voomisupply.com\/products\/value-collection-kp66144-hex-lock-nut-7-16-20-grade-c-steel-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
