It carries an ASTM A490 material grade, which qualifies it for structural steel joints governed by AISC and RCSC specifications. The bolt is partially threaded with a 1-8 UNC thread pattern and measures 3 inches under the head. The bright, uncoated finish makes it suitable for dry or controlled-environment installations where surface treatment is specified separately by the engineer of record. Structural ironworkers, steel erectors, and commercial contractors are the primary installers of this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in heavy structural steel applications including moment frames, column base plates, beam-to-column connections, and braced frames in commercial and industrial construction. The ASTM A490 designation indicates a quenched-and-tempered alloy steel fastener with minimum tensile strength significantly higher than standard Grade 5 or Grade 8 hardware. It is sold individually and is appropriate where job-site control of fastener grade and traceability is required by the structural drawings or inspection protocol.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A490 grade alloy steel construction for high-strength structural bolting\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread standard for compatibility with standard structural nut and washer sets\u003c\/li\u003e\n  \u003cli\u003e3-inch length measured under the head for precise grip-length selection\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank to maximize shear capacity in the bearing zone\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no additional coating to affect dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eSold as single unit for controlled, quantity-specific procurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in structural steel bolted connections requiring ASTM A490 high-strength fasteners per RCSC Specification for Structural Joints, typically paired with heavy hex nuts and hardened washers of matching specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of ASTM A490 structural bolts must be performed by qualified ironworkers or steel erectors in accordance with the RCSC Specification for Structural Joints and applicable building code requirements. Bolt assemblies should be inspected for grade markings and stored to prevent contamination before installation. Pre-installation verification of rotational capacity is required when specified by the structural engineer. Do not substitute A490 bolts with lower-grade hardware, and do not apply paint, lubricants, or coatings not specified by the engineer of record, as these can affect pretension values.\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 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: A490\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM A490\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: 1.418 pounds\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: HCI41000300N-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716222091570,"sku":"HCI41000300N-005BX","price":18.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82b223315f35a321274ed8844f3145e0.jpg?v=1788523283","url":"https:\/\/voomisupply.com\/products\/value-collection-hci41000300n-005bx-hex-head-bolt-a490","provider":"Voomi Supply","version":"1.0","type":"link"}
