It features a 1-1\/8-7 UNC thread size and a 5.5-inch length under head, with partial threading along the shank. Manufactured from steel to ASTM A325 structural bolt standards, this fastener delivers the tensile strength and reliability required in load-bearing connections. The bright uncoated finish reflects the as-manufactured steel surface. Licensed tradespeople and structural ironworkers rely on this bolt where specification compliance and consistent mechanical performance are critical.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for structural steel connections in commercial and industrial construction, bridge work, and heavy equipment assembly where ASTM A325 grade fasteners are called out by engineers or building codes. The 1-1\/8-inch diameter and partial threading make it appropriate for bolted moment frames, shear connections, and similar high-load joint configurations. It is sold individually, making it a practical option for replacement, repair, or low-volume work where a full box quantity is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A325 structural bolt standard — meets strength requirements for engineered steel connections\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-7 UNC thread form for consistent thread engagement with standard heavy hex nuts\u003c\/li\u003e\n  \u003cli\u003e5.5-inch length under head accommodates thicker material stacks in structural joints\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a bearing surface in the grip zone\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for painted, galvanized, or dry interior structural applications\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit — no minimum box quantity required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in structural steel assemblies specifying ASTM A325 hex head bolts at 1-1\/8-7 UNC thread size with a 5.5-inch grip length under head.\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 in accordance with AISC and applicable building code requirements. Power down or de-energize any adjacent systems before working in proximity to electrical equipment. Proper pretensioning — whether by turn-of-nut, calibrated wrench, or direct-tension-indicator method — must follow project specifications; do not apply torque values not defined by the engineer of record or approved installation procedure. Inspect bolt, nut, and washer condition before installation and discard any fasteners showing thread damage or corrosion.\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: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\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  \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: HCI31120550N-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707522416946,"sku":"HCI31120550N-005BX","price":24.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6148b005c55adefbede627bfaf3895b8_19c43b24-8f2a-4b36-aa37-95aef2abe7b4.jpg?v=1788440777","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31120550n-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
