Manufactured from Grade 2 steel with a bright, uncoated finish, this nut meets ANSI ASME B18.2.2 dimensional standards. It carries a 2-1\/2-4 thread size, meaning a 2.5-inch nominal diameter with 4 threads per inch. The width across flats measures 3.875 inches and the height is approximately 1.453 inches, placing it firmly in the heavy structural fastener category. Installation is performed by licensed tradespeople and structural mechanics working on industrial piping, structural steel connections, and heavy mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is suited for use in industrial, commercial, and infrastructure applications where large-diameter fasteners are required. Typical scenarios include structural steel framing, heavy equipment mounting, large-bore pipe flange connections, and mechanical equipment bases. The bright uncoated finish is appropriate for dry or controlled interior environments. Applications requiring corrosion resistance in outdoor or wet service conditions should evaluate whether an additional coating or alternative material is needed before specifying this nut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-1\/2-4 UN right-hand thread for compatibility with standard large-diameter bolting\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate strength for general-purpose structural and mechanical use\u003c\/li\u003e\n  \u003cli\u003eWidth across flats of 3.875 inches and width across points of 4.474 inches for standard wrench sizing\u003c\/li\u003e\n  \u003cli\u003eHeight of 1.453 inches for full thread engagement on heavy fastener applications\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI ASME B18.2.2 fastener dimensional standards\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for controlled interior environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use hex nut for structural bolting applications requiring a 2-1\/2-4 UN thread specification per ANSI ASME B18.2.2.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified tradespeople familiar with large-diameter fastener torquing procedures and applicable structural or mechanical codes. De-energize and isolate all connected systems before performing fastener service on mechanical or electrical equipment. Use properly sized hand or hydraulic torque wrenches rated for large-diameter fasteners. Do not exceed the fastener grade rating by substituting this nut on high-strength bolt assemblies that require Grade 5, Grade 8, or equivalent specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-1\/2-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\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: 3.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 4.474 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.453 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI ASME B18.2.2\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: 250NJP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51719293600050,"sku":"250NJP","price":76.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4366d6049a43d8a3d9d8d655c5dbdf4a.jpg?v=1788558670","url":"https:\/\/voomisupply.com\/products\/value-collection-250njp-hex-nut-2-1-2-4-grade-2-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
