Jam nuts are thin hex nuts used to lock a standard nut in place or secure a threaded fastener where minimal vertical clearance is available. This nut measures 1-1\/8 inches across the flats and 0.4219 inches in height, with a right-hand thread direction conforming to Unified National Fine (UNF) standards. At 0.03 pounds, it is well suited for general mechanical and structural fastening applications where a Grade 2 steel fastener meets the load requirements.\u003c\/p\u003e\n\u003cp\u003eThis jam nut is used across a broad range of mechanical assembly, maintenance, and fabrication tasks in industrial, commercial, and trade settings. Common applications include HVAC equipment assembly, plumbing and piping support structures, electrical enclosure mounting, and general sheet metal or structural work. The fine 3\/4-16 thread pitch provides precise adjustment and strong locking capability, making it a practical choice for lock-nut installations on threaded rod, bolts, and adjustment mechanisms where vibration resistance is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF right-hand thread for precise engagement and secure locking\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate tensile strength for general-purpose fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion resistance in dry or mildly humid environments\u003c\/li\u003e\n  \u003cli\u003eLow-profile jam nut geometry at 0.4219 inches height for tight-clearance installations\u003c\/li\u003e\n  \u003cli\u003e1-1\/8 inch width across flats fits standard 1-1\/8 inch hex wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock jam nut for any threaded fastener application requiring a 3\/4-16 UNF right-hand thread pattern with a 1-1\/8 inch hex profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 1-1\/8 inch open-end wrench, box wrench, or socket. Tighten the jam nut against the primary nut or seating surface while holding the primary fastener stationary to prevent co-rotation. Inspect threads for damage or contamination before installation. Grade 2 steel is not rated for high-temperature or high-stress structural connections governed by ASTM or SAE specifications requiring higher material grades.\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\/4-16\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: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.4219 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 330490BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698109776178,"sku":"330490BR","price":2103.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7de82c5d820ef9c7abf37dee5d0f280a.jpg?v=1788357846","url":"https:\/\/voomisupply.com\/products\/value-collection-330490br-jam-nut-3-4-16-unf-grade-2-zinc-plated","provider":"Voomi Supply","version":"1.0","type":"link"}
