Manufactured from steel with a hot-dipped galvanized finish, this bolt measures 3-3\/4 inches in length under the head and carries a 1-1\/8-7 UNC thread. It is partially threaded, which is standard for structural bolting where the shank bears load across the grip length. The ASTM A325 designation indicates it meets the mechanical property requirements for high-strength structural bolts, making it suitable for steel-to-steel connections in construction and industrial assembly. Weight is 2.09 pounds per package.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in structural steel framing, beam-to-column connections, heavy equipment mounting, and other applications governed by AISC or similar structural codes. The hot-dipped galvanized finish provides corrosion resistance suitable for exterior and corrosive-environment installations. Ironworkers, structural steel contractors, and millwrights typically work with A325 fasteners in these settings. The 1-1\/8-7 thread size is a larger-diameter specification common in heavy structural assemblies where high clamping force is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade A325 high-strength structural bolt meeting ASTM A325 standard\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish for corrosion resistance in exterior and industrial environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for load-bearing grip in structural connections\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-7 UNC thread for compatibility with standard heavy structural hardware\u003c\/li\u003e\n  \u003cli\u003e3-3\/4 inches length under head accommodates thicker steel connection stacks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use structural fastener for applications requiring ASTM A325 high-strength hex head bolts in 1-1\/8-7 UNC thread size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of A325 structural bolts should be performed by qualified ironworkers or structural steel contractors following AISC and applicable building code requirements. Bolts must be installed with matching A325 nuts and hardened washers as required by the connection design. Use calibrated torque wrenches or an approved turn-of-nut method per the applicable structural specification. Never reuse A325 bolts that have been fully tensioned, as they may not be re-tensioned reliably.\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: 3-3\/4 inches\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\u003eThread Style\u003c\/strong\u003e: Partially Threaded\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: 2.09 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: HCI31120375NG-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715554574642,"sku":"HCI31120375NG-005BX","price":28.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28c028effd645153aeebeb12feab8b01.jpg?v=1788515536","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31120375ng-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
