The distorted thread profile creates resistance against loosening caused by vibration and torque, eliminating the need for a separate locking element. The nut carries a zinc and wax plated finish that provides basic corrosion resistance for general-purpose fastening applications. The 3\/4-inch width across flats fits standard hex tooling. This fastener is used by HVAC technicians, plumbers, electricians, and general tradespeople wherever a reliable, self-locking nut is needed in a threaded assembly.\u003c\/p\u003e\n\u003cp\u003eThe MPC712208 is suited for light to medium-duty fastening tasks in residential and commercial mechanical, electrical, and plumbing installations. The 1\/2-13 UNC thread specification is one of the most common coarse-thread sizes in trade work, making this nut a standard fit across a wide range of equipment mounting, bracketing, and structural fastening scenarios. The package contains 25 nuts, making it practical for service trucks, job-site bins, and maintenance stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDistorted thread design resists loosening under vibration without a secondary locking element\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread — one of the most widely used thread sizes in trade applications\u003c\/li\u003e\n  \u003cli\u003eGrade B steel construction for general-purpose fastening duty\u003c\/li\u003e\n  \u003cli\u003eZinc and wax plated finish for basic corrosion and galling resistance\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch width across flats fits standard hex wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-count package for stocking and job-site use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2-13 UNC threaded fasteners and bolts in general mechanical, HVAC, plumbing, and electrical installation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard 3\/4-inch open-end, box, or socket wrench. Distorted thread lock nuts are typically single-use — once fully torqued and removed, the locking effectiveness may be reduced and replacement is recommended. Always de-energize and isolate equipment before accessing fastener assemblies on live systems. Follow applicable codes such as NEC, IPC, or IFGC as relevant to the system being serviced.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Grade B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut with Distorted Thread\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc and Wax Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\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: MPC712208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710032281906,"sku":"MPC712208","price":18.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fa4aaadd817a838c98ad0c0433f4597.jpg?v=1788463359","url":"https:\/\/voomisupply.com\/products\/value-collection-mpc712208-hex-lock-nut-1-2-13-unc-grade-b-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
