Jam nuts are thin profile nuts used to lock a standard hex nut in place or to secure a fastener in applications where a full-height nut would not fit. At 5\/16 inch tall with a 7\/8 inch width across flats, this nut threads onto standard 9\/16-18 right-hand UNF fasteners. The zinc plating provides basic corrosion resistance for general indoor and light-duty outdoor applications. This part is sold individually, with a minimum order quantity of 25 pieces.\u003c\/p\u003e\n\u003cp\u003eThis jam nut is suited for general mechanical assembly, maintenance, and fabrication work across HVAC, plumbing, electrical, and light industrial trades. It is commonly used as a locknut on threaded rod, valve stems, and panel hardware where a reduced-height fastener is needed. The 9\/16-18 UNF thread is a fine-thread designation, offering stronger thread engagement per inch compared to coarse-thread equivalents, making it a frequent choice in precision assemblies and vibration-prone environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16-18 UNF fine right-hand thread for strong thread engagement\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for basic corrosion protection\u003c\/li\u003e\n  \u003cli\u003eJam nut profile at 5\/16 inch height — lower profile than a standard hex nut\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch width across flats for use with standard 7\/8 inch wrenches or sockets\u003c\/li\u003e\n  \u003cli\u003eSold individually; minimum order quantity of 25 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 9\/16-18 UNF threaded fasteners, threaded rod, and hardware requiring a right-hand fine-thread jam nut in Grade 2 steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard 7\/8 inch open-end wrench, box wrench, or socket. When used as a locknut, thread the jam nut against a primary nut and tighten the two nuts against each other to prevent loosening. Do not exceed the load ratings appropriate for Grade 2 steel fasteners. Ensure threads are clean and free of debris before installation to avoid cross-threading.\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: 9\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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 Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 330450PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722196091186,"sku":"330450PS","price":1164.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/537c46af39ea9ada84bfadc0829ec47d.jpg?v=1788587172","url":"https:\/\/voomisupply.com\/products\/value-collection-330450ps-hex-jam-nut-9-16-18-unf-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
