It measures 4-3\/4 inches in length under the head and features partial threading along the shank. The uncoated, bright finish leaves the steel bare for applications where a coating is unnecessary or where field treatment will be applied. At 1 pound per unit, this is a heavy-duty fastener suited for structural steel connections, steel-to-steel joints, and high-strength bolted assemblies. Installation is performed by ironworkers, structural steel fabricators, and qualified mechanical contractors working to project specifications.\u003c\/p\u003e\u003cp\u003eThis bolt is used in structural steel construction, steel frame assemblies, heavy equipment fabrication, and other high-load bolted connections requiring ASTM A325 compliance. The 7\/8-9 UNC thread size is a common heavy structural fastener diameter. Partial threading preserves a smooth shank bearing surface in the grip zone, which is standard practice in structural bolted joints. This fastener ships as a single unit and is appropriate for job-site procurement or shop fabrication use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASTM A325 structural bolt standard for high-strength steel-to-steel connections\u003c\/li\u003e\n\u003cli\u003e7\/8-9 UNC thread form for compatibility with standard structural nuts and washers\u003c\/li\u003e\n\u003cli\u003e4-3\/4 inch length under head for use in deeper grip applications\u003c\/li\u003e\n\u003cli\u003ePartial threading preserves shank bearing surface in the grip zone\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — suitable for galvanizing, painting, or bare use per project specs\u003c\/li\u003e\n\u003cli\u003eSingle-unit packaging for flexible procurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ASTM A325 high-strength structural hex bolt for use in steel-to-steel bolted connections per standard structural fastener specifications.

Tighten using calibrated torque wrenches, turn-of-nut method, or tension-control tooling as specified in the connection design documents. Do not substitute standard hex nuts or light washers where heavy structural hardware is specified. Always consult project structural drawings and the applicable building code before installing structural fasteners.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 4-3\/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\u003eFastener Standard\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: HCI30870475N-001BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690541678898,"sku":"HCI30870475N-001BX","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6148b005c55adefbede627bfaf3895b8_aaeb6e76-3315-4842-9988-a5e423fda631.jpg?v=1788271327","url":"https:\/\/voomisupply.com\/products\/value-collection-hci30870475n-001bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
