It carries a 1-8 thread size with Unified National Coarse (UNC) thread standard and measures 3-1\/2 inches in length under the head. Constructed from Grade A325 steel with a hot-dipped galvanized finish, this bolt meets ASTM A325 structural fastener standards. The partial threading design is standard for structural bolting, allowing the unthreaded shank to bear shear loads across joint interfaces. Installation is typically performed by ironworkers, millwrights, or structural contractors working on code-governed connections.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for heavy structural steel connections in commercial construction, industrial fabrication, and infrastructure projects where ASTM A325 compliance is required. The hot-dipped galvanized finish provides corrosion resistance for outdoor and exposed environments. The 1-8 UNC thread is compatible with standard heavy hex nuts and hardened washers used in structural bolted assemblies. Projects governed by AISC, RCSC, or OSHA structural steel erection requirements commonly specify A325 bolts of this type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A325 certified structural bolt for load-bearing connections\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread size with partial threading for shear-load bearing shank\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inch length under head for deep-grip structural joint applications\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish for corrosion resistance in exposed environments\u003c\/li\u003e\n  \u003cli\u003eGrade A325 steel construction meets recognized structural fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASTM A325 structural hex head bolt for use with heavy hex nuts and hardened washers conforming to ASTM F436 in structural steel bolted connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified structural ironworkers or contractors in accordance with RCSC Specification for Structural Joints Using High-Strength Bolts and applicable building codes. Shut down and lock out any equipment or suspended loads in the work area before performing bolted connections. Use calibrated torque wrenches or tension-control tooling as required by the project specification and the bolt pretensioning method specified. Do not reuse A325 bolts that have been fully tensioned unless permitted by the engineer of record.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8\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: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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: 1.526 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: HCI31000350NG-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692880331058,"sku":"HCI31000350NG-005BX","price":28.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fb0530577393bbc789d04a631fd24a1.jpg?v=1788304433","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31000350ng-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
