It features a 1-1\/8-7 UNC thread pattern with a 4.25-inch length under the head and partial threading along the shank. The bolt is manufactured from steel with a hot-dipped galvanized finish, providing corrosion resistance in exposed or outdoor installations. Conforming to ASTM A325 standards, this fastener meets the mechanical property requirements expected in structural steel assembly work. It is installed by ironworkers, structural mechanics, and millwrights using standard impact or torque tooling appropriate to the application.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for structural steel connections in commercial and industrial construction, heavy equipment assembly, and similar high-load bolted joint applications. The ASTM A325 designation makes it appropriate where structural bolt specifications are called out in engineering drawings or project specifications. The hot-dipped galvanized finish extends service life in exterior or high-humidity environments where bare steel would be prone to oxidation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade A325 structural steel construction meeting ASTM A325 fastener standard\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-7 UNC thread size for high-torque, high-clamping-force applications\u003c\/li\u003e\n  \u003cli\u003e4.25-inch length under head for use in thick structural member stack-ups\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for proper bearing and shear load transfer\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish for corrosion resistance in outdoor or wet environments\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; individually packaged (Qty 1 per package)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ASTM A325-compliant structural hex head bolt for use in standard inch-series bolted connections where 1-1\/8-7 UNC thread and 4.25-inch grip length requirements are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified tradespeople familiar with structural bolting procedures per applicable codes and project engineering specifications. Follow the specified pretension or snug-tight requirements for ASTM A325 bolts as outlined in the applicable structural steel standard for the project. Use appropriate impact wrenches, torque wrenches, or turn-of-nut tooling suitable for large-diameter structural fasteners. Inspect threads and galvanized coating for damage before installation and do not install fasteners with stripped threads or compromised coating.\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\/8-7\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: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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\u003eFinish\u003c\/strong\u003e: Hot-Dipped Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A325\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: 2.212 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HCI31120425NG-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698534449458,"sku":"HCI31120425NG-005BX","price":29.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfc0a95d7f08a3d3944b599746bade3e.jpg?v=1788364348","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31120425ng-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
