It features a 1-1\/8-7 UNC thread size with a 4-1\/2 inch length under head and a partially threaded shank. Constructed from uncoated steel meeting ASTM A325 standards, this bolt delivers the high-strength performance required in structural steel connections, heavy equipment assembly, and industrial framing work. Its bright, uncoated finish is suitable for applications where a secondary coating will be applied or where bare steel is acceptable for the environment.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in structural steel construction, bridge fabrication, heavy machinery assembly, and industrial fabrication where ASTM A325 high-strength fasteners are specified by engineers or building codes. The partially threaded shank provides a bearing surface in the grip zone, which is critical for shear-loaded joint applications common in steel-to-steel connections. It is typically installed by ironworkers, millwrights, and mechanical contractors working to structural specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A325 high-strength structural bolt standard\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-7 UNC thread for compatibility with standard heavy-duty nuts and hardware\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a clean bearing surface in the grip zone\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch length under head accommodates thick material stack-ups\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for field-coating or bare steel applications\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for use with standard imperial 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 with standard 1-1\/8 inch heavy hex nuts and hardened washers in structural steel connections per applicable engineering specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified ironworkers or structural mechanics following AISC and RCSC specifications for high-strength bolted connections. Always use the appropriate heavy hex nut and hardened washer as required by the joint design. De-energize and lock out any associated equipment before working in the installation area. Do not use impact tools without verifying compatibility with the specified tightening method, whether snug-tight, pretensioned, or slip-critical.\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: 4-1\/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\u003eStandard\u003c\/strong\u003e: ASTM A325\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\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: HCI31120450N-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690599678258,"sku":"HCI31120450N-005BX","price":21.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6148b005c55adefbede627bfaf3895b8_ec6765e3-370a-4971-81e3-97bb5b924b38.jpg?v=1788272395","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31120450n-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
