It measures 5.5 inches in length under the head and features a hot-dipped galvanized finish for corrosion resistance in demanding environments. The bolt is partially threaded, which is standard for structural connections where clamping force is distributed through the unthreaded shank. At 0.678 pounds, this is a heavy-duty fastener suited for steel-to-steel connections in structural and industrial applications. Licensed trades including ironworkers, steel erectors, structural contractors, and mechanical trades install this type of hardware on job sites governed by AISC and related structural codes.\u003c\/p\u003e\n\u003cp\u003eThis bolt is designed for structural steel connections, heavy equipment assembly, bridge fabrication, and industrial framing applications. The 5\/8-11 UNC thread specification and A325 material grade make it a go-to fastener wherever high-strength structural bolting is specified by an engineer or project drawing. The hot-dipped galvanized finish extends service life in exterior, high-humidity, and corrosive environments. It is packaged and sold individually, making it appropriate for replacement hardware, maintenance stock, or supplemental quantities on a project.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread size 5\/8-11 UNC for compatibility with standard structural nuts and washers\u003c\/li\u003e\n  \u003cli\u003e5.5 inch length under head provides grip length suitable for thick structural connections\u003c\/li\u003e\n  \u003cli\u003eSteel construction meeting ASTM A325 high-strength structural bolt specification\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish delivers corrosion resistance for exterior and industrial use\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank concentrates clamping force and resists shear loads in bearing-type connections\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for maintenance, repair, and small-quantity needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-strength structural hex head bolt per ASTM A325, compatible with 5\/8-11 UNC heavy hex nuts and structural flat washers used in standard steel-to-steel bolted connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified trades following AISC Specification for Structural Steel Buildings and applicable project specifications. Power down or de-energize adjacent systems before working in energized structural bays. Use calibrated torque wrenches or tension-control methods as required by the connection type and project engineer of record. Do not reuse A325 bolts that have been fully tensioned, as they are not rated for re-tensioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\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\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\u003eStandard\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: Hot-Dipped Galvanized\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: 0.678 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: HCI30620550NG-010BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707895578930,"sku":"HCI30620550NG-010BX","price":18.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf1f66d1e55eeb870273d4c4ac4cab59.jpg?v=1788442755","url":"https:\/\/voomisupply.com\/products\/value-collection-hci30620550ng-010bx-hex-head-bolt-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
