It is manufactured from Grade A325 steel with a hot-dipped galvanized finish, providing corrosion resistance in exposed or outdoor environments. The bolt measures 4.5 inches in length under the head and features partial threading, which is standard for structural bolts where the shank must bear shear loads in the grip area. At 0.90 pounds, this is a substantial fastener suited for ironwork, structural steel connections, and heavy mechanical assemblies installed by ironworkers, millwrights, and structural contractors.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in structural steel connections, beam-to-column assemblies, heavy equipment mounting, and similar high-load applications where ASTM A325 compliance is specified by engineering drawings or code. The hot-dipped galvanized finish makes it appropriate for exterior structural work, bridge components, utility structures, and other installations exposed to moisture or corrosive environments. Partial threading ensures the unthreaded shank spans the shear plane of the joint, meeting standard structural bolt installation practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade A325 steel meets ASTM A325 structural bolt standard for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish provides durable corrosion resistance for exterior and exposed applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows the unthreaded body to carry shear loads across the grip length\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC thread is a common structural bolt size compatible with standard hex nuts and washers\u003c\/li\u003e\n  \u003cli\u003e4.5-inch length under head suits typical multi-ply structural steel and heavy base plate connections\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; sold individually for low-quantity procurement flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ASTM A325-compliant structural hex head bolt for use with standard 3\/4-10 UNC heavy hex nuts and F436 structural washers in steel-to-steel bolted connections per applicable structural codes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of ASTM A325 structural bolts must be performed by qualified ironworkers or structural contractors in accordance with AISC and RCSC Specification for Structural Joints requirements. Snug-tighten all bolts in the joint before progressing to final pretensioning. Do not use impact tools that have not been calibrated for the required pretension level, and do not reuse A325 bolts that have been fully pretensioned. Galvanized bolts should be paired with galvanized nuts that have been lubricated per ASTM A563 requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10\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: 4.5 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\u003eFinish\u003c\/strong\u003e: Hot-Dipped Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A325\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement System\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.90 pounds\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: HCI30750450NG-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698067308850,"sku":"HCI30750450NG-005BX","price":15.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c47a983ca568d6dce6e035a093e47685.jpg?v=1788357304","url":"https:\/\/voomisupply.com\/products\/value-collection-hci30750450ng-005bx-hex-head-bolt-3-4-10","provider":"Voomi Supply","version":"1.0","type":"link"}
