It features a 1-1\/4-7 UNC thread and a 4-inch length measured under the head. Manufactured from steel to ASTM A325 material grade standards, this bolt is partially threaded and carries a bright uncoated finish. It is suited for high-strength bolted connections where ASTM A325 compliance is required, including steel-to-steel structural assemblies. Installation is handled by ironworkers, structural mechanics, or general contractors working to applicable structural codes.\u003c\/p\u003e\n\u003cp\u003eThis bolt is commonly used in structural steel construction, heavy equipment fabrication, and industrial installations that require ASTM A325 rated fasteners. The 1-1\/4-7 UNC thread size and 4-inch under-head length make it appropriate for thick connection plates and flange joints where partial threading provides a clean bearing shank in the grip zone. It is sold individually and is suitable for both new construction and retrofit structural connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A325 material grade for high-strength structural bolting\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-7 UNC thread for compatibility with standard structural nut and washer sets\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head accommodates thick connection members\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a clean grip zone to resist shear loads\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for use in dry or protected structural environments\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for use with imperial hardware and tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ASTM A325 compliant high-strength hex head bolt for use with standard 1-1\/4-7 UNC heavy hex nuts and structural washers in imperial-system bolted connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural mechanics following AISC and RCSC specifications for high-strength bolted connections. Always de-energize or isolate any nearby electrical or mechanical systems before working in the connection area. Use calibrated torque wrenches or tension-control tools appropriate for the bolt diameter and specified pretension. Do not reuse A325 bolts that have been fully tensioned without verifying acceptability per the applicable structural specification.\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: 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\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\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 pound\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: HCI31250400N-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695701852466,"sku":"HCI31250400N-005BX","price":28.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d3f0904b24269a44554ece56b0f5a43_d7c09fbe-5188-4546-ab59-66c52a8abd1c.jpg?v=1788337559","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31250400n-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
