Manufactured from Grade 2, Grade A steel with a bright uncoated finish, this nut features a 3-12 thread size with a right-hand thread direction conforming to UN thread standards. At 4.5 inches across the flats and a height of approximately 2-37\/64 inches, this is a large-format nut suited for demanding bolted connections. Licensed trade workers in mechanical, industrial maintenance, and construction fields regularly specify this size for heavy equipment and structural work.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is appropriate for use in general industrial fastening, structural steel connections, heavy machinery assembly, and maintenance applications where a large-diameter UN-threaded fastener is required. Its Grade 2 material classification makes it suitable for non-critical structural and mechanical assemblies that do not require higher-grade alloy fasteners. The uncoated finish is compatible with environments where a protective coating is applied after installation or where bare steel is acceptable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-12 thread size with right-hand UN thread standard\u003c\/li\u003e\n  \u003cli\u003eGrade 2, Grade A steel construction for reliable general-purpose strength\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for post-installation coating or bare-steel applications\u003c\/li\u003e\n  \u003cli\u003e4.5 inches across flats for use with large-format wrenches and torque tools\u003c\/li\u003e\n  \u003cli\u003eHeight of approximately 2-37\/64 inches providing full thread engagement depth\u003c\/li\u003e\n  \u003cli\u003eDoes not meet military specifications — intended for commercial and industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3-12 UN right-hand threaded bolts and studs in general industrial and structural fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or trades professional familiar with large-diameter fastener torque requirements. Always verify thread engagement and alignment before applying final torque. Use appropriate large-format wrenches or torque equipment rated for the fastener size. Ensure mating bolt or stud material grade is compatible with Grade 2 hardware to avoid mismatched joint strength.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\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, Grade A\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: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2-37\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.05 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: HNFI300-001BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699818758450,"sku":"HNFI300-001BX","price":87.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b7c114688694bc84cd923b64ecf1775.jpg?v=1788381496","url":"https:\/\/voomisupply.com\/products\/value-collection-hnfi300-001bx-hex-nut-3-12-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
