It features a 7\/8-9 UNC thread with a 5.5-inch length under head and is partially threaded along the shank. Manufactured from steel to the A325 material grade and finished with a hot-dipped galvanized coating, this bolt is built to resist corrosion in demanding environments. It conforms to ASTM A325 standards, making it appropriate for structural steel connections and high-strength bolted assemblies. Licensed tradespeople and contractors working with structural steel rely on this grade for code-compliant connections.\u003c\/p\u003e\n\u003cp\u003eThis hex head bolt is suited for structural steel construction, heavy equipment fabrication, bridge work, and commercial or industrial building projects where high-strength fasteners are required. The partial threading is standard for structural bolted joints where the unthreaded shank bears the shear load. The hot-dipped galvanized finish extends service life in outdoor, high-humidity, and weather-exposed installations. Ironworkers, structural contractors, and mechanical contractors commonly specify A325 bolts for beam-to-column connections and similar load-bearing assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread size for compatibility with standard structural hardware\u003c\/li\u003e\n  \u003cli\u003e5.5-inch length under head accommodates thicker structural members and connection stacks\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank designed for shear-bearing structural joints\u003c\/li\u003e\n  \u003cli\u003eSteel construction with A325 material grade for high-strength performance\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish provides enhanced corrosion resistance in outdoor and wet environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A325 fastener standard for structural steel applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style structural fastener for use with standard 7\/8-inch heavy hex nuts and washers in ASTM A325-compliant bolted connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified ironworkers or structural contractors in accordance with the AISC specification and applicable local building codes. Shut down or isolate any energized equipment or live loads before working in the connection zone. Use calibrated torque wrenches or the turn-of-nut method as specified by the engineer of record — do not substitute arbitrary torque values. Inspect the galvanized coating for damage before installation and replace any bolts with compromised coating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 5.5 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: A325\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Hot-Dipped Galvanized\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: 1.46 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: HCI30870550NG-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693506462002,"sku":"HCI30870550NG-005BX","price":22.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb76302816e446fa95b1a2444d905e03.jpg?v=1788313362","url":"https:\/\/voomisupply.com\/products\/value-collection-hci30870550ng-005bx-hex-head-bolt-7-8-9","provider":"Voomi Supply","version":"1.0","type":"link"}
