It features a 7\/8-9 thread (UNC standard) and a 3-1\/4 inch length under head with partial threading. The uncoated, bright finish leaves the steel in its natural state, which is typical for high-strength structural applications where coating would interfere with load calculations or inspection. This fastener is installed by structural ironworkers, steel erectors, and industrial maintenance mechanics working on bolted structural steel connections.\u003c\/p\u003e\u003cp\u003eThis bolt is suited for heavy structural and industrial bolted joint assemblies requiring a certified high-strength fastener. ASTM A490 designates a quenched-and-tempered alloy steel hex bolt engineered for structural steel connections in commercial, industrial, and infrastructure construction. Partial threading keeps the shank smooth across the bearing zone of the joint, which is the correct configuration for most slip-critical and bearing-type connections where thread engagement in the shear plane must be avoided.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASTM A490 certified high-strength structural hex bolt\u003c\/li\u003e\n\u003cli\u003e7\/8-9 UNC thread for standard structural connection hardware\u003c\/li\u003e\n\u003cli\u003e3-1\/4 inch length under head, partially threaded for shear-zone integrity\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish for direct use or field inspection per ASTM requirements\u003c\/li\u003e\n\u003cli\u003eInch measurement system for compatibility with standard structural hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for structural steel bolted connections requiring ASTM A490 high-strength hex bolts in 7\/8-9 UNC thread size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of ASTM A490 structural bolts must be performed by qualified personnel in accordance with the AISC Specification for Structural Steel Buildings and applicable project specifications. Power down or de-energize any adjacent electrical systems before working in structural assemblies where such hazards exist. Use calibrated torque wrenches or tension-control tools as required by the connection design — do not substitute standard installation torque values without engineering approval. Inspect bolt markings and lot certifications before installation to confirm ASTM A490 compliance.\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: 3-1\/4 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: A490\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A490\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated \/ Bright\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: 1.079 pounds\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: HCI40870325N-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692129976626,"sku":"HCI40870325N-005BX","price":16.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6148b005c55adefbede627bfaf3895b8_32066198-a447-45a6-b6c1-2b3682b22809.jpg?v=1788293500","url":"https:\/\/voomisupply.com\/products\/value-collection-hci40870325n-005bx-hex-head-bolt-a490","provider":"Voomi Supply","version":"1.0","type":"link"}
