It features a 1-8 UNC thread size with a 3-3\/4 inch length measured under the head and a partially threaded shank. The bright, uncoated finish leaves the steel bare for applications where galvanic compatibility or field coating is required. At approximately 1 pound, this bolt is sized for load-bearing structural connections in commercial and industrial fastening work. Tradespeople in structural steel erection, mechanical contracting, and heavy equipment installation will encounter this bolt in high-strength joint assemblies.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for structural steel connections, beam-to-column joints, and heavy mechanical assemblies where ASTM A325 high-strength fastener specifications are required. The partially threaded shank provides a bearing surface in the bolt grip zone, which is critical in shear-loaded structural connections. It is commonly specified by ironworkers, structural contractors, and millwrights working to AISC or project-specific structural drawings that call out A325 high-strength bolts in inch series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A325 certified high-strength structural bolt for load-bearing applications\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread form with partially threaded shank for proper grip-zone bearing\u003c\/li\u003e\n  \u003cli\u003e3-3\/4 inch length under head measured per standard length convention\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — compatible with field coating or hot-dip galvanizing processes\u003c\/li\u003e\n  \u003cli\u003eSteel construction meeting ASTM A325 material grade requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ASTM A325 high-strength hex head bolt for use in structural steel connections requiring 1-8 UNC inch-series fasteners with a 3-3\/4 inch grip length under head.

Shut down and de-energize any adjacent electrical or mechanical systems before working in the bolt zone. Do not reuse A325 bolts that have been fully tensioned, as they are not rated for re-tensioning in most structural applications. Always torque or tension to the specification called out on the structural drawings — do not estimate preload by feel.\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: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\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: Bright \/ Uncoated\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 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: HCI31000375N-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717129011506,"sku":"HCI31000375N-005BX","price":15.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6148b005c55adefbede627bfaf3895b8_4a244c6a-0fc6-437c-a8ec-39f7fdc7746d.jpg?v=1788536082","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31000375n-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
