Jam nuts are thin hex nuts used to lock a standard nut in place or to secure a fastener in a fixed position against vibration or movement. This nut features right-hand threading and measures 7\/16 inches across the flats with a height of 0.1563 inches. The zinc coating provides basic corrosion resistance suitable for general indoor and light-duty outdoor applications. Installation requires a standard 7\/16-inch wrench or socket. Sold individually, with a minimum order quantity of 100 units.\u003c\/p\u003e\u003cp\u003eThis jam nut is suited for general mechanical assembly, HVAC equipment panels, electrical enclosures, plumbing fixture mounting, and similar light-to-medium fastening applications where a low-profile locking nut is required. The 1\/4-28 UNF fine thread provides tighter thread engagement compared to coarse-thread equivalents, making it a common choice in vibration-prone assemblies and precision hardware applications across trade industries.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-28 UNF fine thread for tighter engagement in vibration-prone assemblies\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction for general-purpose mechanical applications\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eLow-profile jam nut design at 0.1563 inches tall for space-constrained installations\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, standard orientation\u003c\/li\u003e\n\u003cli\u003e7\/16-inch across-flats dimension compatible with standard hex wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-28 UNF jam nut suitable for general-purpose fastening applications requiring a Grade 2 steel, zinc-plated low-profile hex nut.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and tighten with a 7\/16-inch wrench or socket. Jam nuts are typically threaded on first, followed by a standard nut that is torqued down and then back-tightened against the jam nut to create a locking pair. Ensure mating threads are clean and free of debris before installation. Do not use in applications requiring military-specification fasteners.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\/4-28\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\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.1563 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\u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\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: 330350PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718141018418,"sku":"330350PS","price":486.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/317c38d2b53b4a5f5165a74bf0f8cceb.jpg?v=1788550252","url":"https:\/\/voomisupply.com\/products\/value-collection-330350ps-1-4-28-unf-grade-2-zinc-jam-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
