Jam nuts are thinner than standard hex nuts and are used to lock a primary nut in place or to secure threaded rod and stud assemblies where axial space is limited. This nut measures 2-1\/4 inches across the flats and 0.8438 inches in height. The right-hand thread direction follows standard UNC convention. Plumbers, pipefitters, millwrights, and general maintenance trades commonly use fasteners of this type in structural and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis jam nut is suited for industrial, commercial, and trade applications where a large-diameter UNC fastener is required. Typical uses include securing threaded rod assemblies, locking against primary nuts on bolted connections, and general mechanical fabrication. The bright uncoated finish is appropriate for indoor or protected environments where corrosion exposure is minimal. Applications span HVAC equipment mounting, pipe hanger assemblies, and structural bracketing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-6 UNC right-hand thread — standard coarse-thread pitch for large-diameter fastener applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate strength for general mechanical and structural use\u003c\/li\u003e\n  \u003cli\u003eJam nut profile at 0.8438 inches height allows use in tight axial-clearance installations\u003c\/li\u003e\n  \u003cli\u003e2-1\/4 inches across flats — accepts standard open-end or combination wrenches sized for this hex dimension\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no additional coating that could interfere with thread engagement tolerances\u003c\/li\u003e\n  \u003cli\u003eDoes not meet military specifications — intended for commercial and trade applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1-1\/2-6 UNC threaded fastener assemblies including threaded rod, bolts, and studs following UNC coarse-thread standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand-threading the nut onto the mating fastener and tightening with an appropriate open-end or combination wrench sized for a 2-1\/4-inch hex. When used as a jam nut, thread the jam nut against the primary nut and hold the primary nut stationary while torquing the jam nut into contact. Inspect mating threads for damage or contamination before assembly. Follow applicable mechanical and structural codes for fastener torque requirements based on the specific application and Grade 2 material rating.\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: 1-1\/2-6\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: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.8438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\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: 329310BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716405297458,"sku":"329310BR","price":44.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83797c4508794ecc62e5338e64eba45a.jpg?v=1788525554","url":"https:\/\/voomisupply.com\/products\/value-collection-329310br-hex-jam-nut-1-1-2-6-unc-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
