Jam nuts are thinner than standard full hex nuts and are used to lock a primary nut in place or to secure a fastener in applications where a reduced profile is required. This nut features a right-hand thread and measures 1-5\/16 inches across the flats with a height of approximately 0.4844 inches. At 0.02 pounds, it is a lightweight hardware component suited for general mechanical and structural assembly work performed by maintenance technicians, millwrights, and general contractors.\u003c\/p\u003e\u003cp\u003eThis jam nut is appropriate for general-purpose fastening applications in light industrial, commercial, and residential construction settings. The 7\/8-9 UNC thread size and Grade 2 steel construction make it suitable for non-critical clamping and locking applications where high-strength fastener grades are not required. It is commonly used in equipment assemblies, frames, and fixture mounting where a thin locking nut is specified. This item is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC right-hand thread for standard North American fastener compatibility\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction suitable for general-purpose, non-critical assemblies\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides basic corrosion resistance in mild environments\u003c\/li\u003e\n\u003cli\u003eReduced-height jam nut profile for locking applications with limited clearance\u003c\/li\u003e\n\u003cli\u003e1-5\/16 inches across flats fits standard 7\/8-9 hex wrench tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 7\/8-9 UNC threaded fasteners in general-purpose mechanical and structural assemblies requiring a Grade 2 jam nut.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by maintenance technicians or mechanical tradespeople using standard open-end or box wrenches sized for 1-5\/16 inches across flats. De-energize or shut down any associated equipment before servicing fastener assemblies under load. When used as a locking jam nut, thread the jam nut against the primary nut and torque both simultaneously to prevent backing off — do not over-torque Grade 2 hardware beyond application requirements. Follow applicable mechanical and structural codes for the installation context.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9\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\u003eNut Type\u003c\/strong\u003e: Jam Nut\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: 1-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.4844 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161727\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 330210BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693864714546,"sku":"330210BR","price":1170.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d6cb9213cb609f43d966701a655b195.jpg?v=1788318282","url":"https:\/\/voomisupply.com\/products\/value-collection-330210br-hex-jam-nut-7-8-9-grade-2-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
