Jam nuts are thin hex nuts used to lock a standard nut in place or to secure a fastener in applications where a full-height nut is not required. This nut features right-hand threading and measures 9\/16 inches across the flats with a height of 0.2188 inches. It weighs 0.05 pounds per unit and is sold individually, with a minimum order quantity of 100 pieces. Licensed trades and maintenance professionals rely on this type of fastener for general-purpose mechanical assemblies, equipment mounting, and threaded rod applications.\u003c\/p\u003e\n\u003cp\u003eThis jam nut is suited for residential and light commercial applications where Grade 2 steel and an uncoated finish meet the load and environmental requirements. It is commonly used in HVAC equipment mounting, plumbing fixture support brackets, electrical enclosure assemblies, and general mechanical fastening tasks. The 3\/8-16 UNC thread size is one of the most common inch-series thread standards, making this nut widely applicable across maintenance and installation work in the trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC right-hand thread for broad compatibility with standard inch-series fasteners\u003c\/li\u003e\n  \u003cli\u003eJam nut profile at 0.2188 inches tall — thinner than a standard full hex nut for space-constrained locking applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate tensile strength for general-purpose mechanical use\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — suitable for dry or protected indoor environments\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch across-flats dimension fits standard 9\/16-inch wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jam nut compatible with any 3\/8-16 UNC threaded fastener, rod, or stud in standard inch-series mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eJam nuts are typically installed by threading a standard or full hex nut first, then threading the jam nut against it and tightening the two together to create a locking effect. A standard open-end, combination, or socket wrench sized for 9\/16 inches across the flats is required. Ensure mating threads are clean and free of debris before installation. Do not use this fastener in applications requiring corrosion resistance or elevated-temperature service without verifying that Grade 2 uncoated steel meets the applicable engineering or code requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Jam Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.2188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161727\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: 329090PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721104523570,"sku":"329090PR","price":625.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eaabae724402221b3ce3af4a18b932bf.jpg?v=1788573586","url":"https:\/\/voomisupply.com\/products\/value-collection-329090pr-3-8-16-grade-2-jam-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
