This bolt is manufactured from Grade A325 steel with a hot-dipped galvanized finish, providing corrosion resistance in exposed or high-moisture environments. The shank measures 3-1\/4 inches in length under head and is partially threaded, which is standard for structural connection work where bearing-length grip is required. It weighs 1.064 pounds per unit. Licensed trades including ironworkers, structural steel erectors, millwrights, and plumbing and mechanical contractors routinely specify A325 bolts for bolted connections governed by AISC and ASTM standards.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for structural steel connections, equipment mounting, and heavy mechanical assemblies where ASTM A325 material compliance is required. The partially threaded configuration is well matched to applications demanding a defined grip length and full shank bearing in the joint. The hot-dipped galvanized coating makes it appropriate for outdoor, bridge, industrial, and other corrosive-environment installations where bare steel fasteners would degrade prematurely. Each unit is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade A325 steel meeting ASTM A325 fastener standard for structural applications\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish for corrosion resistance in exposed environments\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread size with partial threading for proper grip-length performance\u003c\/li\u003e\n  \u003cli\u003e3-1\/4 inch length under head accommodates typical structural connection stack-ups\u003c\/li\u003e\n  \u003cli\u003eHex head drive for use with standard impact wrenches and torque wrenches\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; compatible with standard UNC tooling and hardware\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 bolted steel connections, equipment bases, and mechanical assemblies requiring 7\/8-9 UNC fasteners with a 3-1\/4 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified tradespeople following applicable structural or mechanical codes, including AISC specifications for structural steel connections. Power down or de-energize any adjacent electrical equipment before working in proximity to energized systems. Use a calibrated torque wrench or tension-control method appropriate for A325 structural bolts, following the engineer-of-record or project specification for the required pretension value. Do not substitute a different grade bolt for an A325-specified connection without engineering approval.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9\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\/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\u003eFinish\u003c\/strong\u003e: Hot-Dipped Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\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: 1.064 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: HCI30870325NG-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694599831858,"sku":"HCI30870325NG-005BX","price":18.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eeb112979e229adcffecbd9867366a91.jpg?v=1788326058","url":"https:\/\/voomisupply.com\/products\/value-collection-hci30870325ng-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
