It carries a 1-1\/4-7 UNC thread size with a 3-3\/4 inch length under the head, manufactured from steel to ASTM A325 structural bolt standards. The hot-dipped galvanized finish provides corrosion resistance for exterior, wet, or high-humidity environments. This bolt is used by ironworkers, structural contractors, millwrights, and mechanical contractors where high-strength, code-compliant fasteners are required.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for structural steel connections, heavy equipment mounting, bridge and building framework, and industrial machinery assembly. The ASTM A325 grade designation makes it appropriate where engineering specifications call out high-strength structural bolts. Full threading along the shank allows engagement across a range of grip lengths and is compatible with heavy hex nuts and structural washers used in steel-to-steel connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A325 grade steel construction meets structural fastener strength requirements\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank provides maximum thread engagement flexibility\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish for corrosion resistance in outdoor and wet conditions\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-7 UNC thread form for compatibility with standard heavy hex nuts\u003c\/li\u003e\n  \u003cli\u003e3-3\/4 inch length under head suits a range of structural grip lengths\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for standard US structural applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-strength structural replacement or new-installation hex bolt for applications specifying ASTM A325 fasteners with a 1-1\/4-7 UNC thread and 3-3\/4 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified ironworkers, structural mechanics, or contractors following applicable structural codes including AISC and RCSC specifications for high-strength bolted connections. Always shut down and de-energize any powered equipment before fastening or retorquing in mechanical installations. Use calibrated torque equipment appropriate for A325 structural bolts and do not substitute standard hex nuts where heavy hex nuts are specified. Inspect galvanized coating for damage before installation in corrosive environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully Threaded\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: A325\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A325\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Hot-Dipped Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.724 pounds\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: HCI31250375NG-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723911659826,"sku":"HCI31250375NG-005BX","price":48.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20537e4d896d12508c7ee8050a82d5a5.jpg?v=1788609807","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31250375ng-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
