This bolt measures 10 inches in length under the head and features a hot-dipped galvanized finish for corrosion resistance in outdoor and high-moisture environments. Manufactured from Grade 2 steel and produced to ASTM A307 standards, it uses a partially threaded shank, which is standard for through-bolting applications where bearing load distribution matters. Tradespeople across construction, mechanical contracting, and general fabrication rely on this bolt type for routine structural connections.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for residential and light commercial construction, equipment mounting, structural framing connections, and general fabrication work where ASTM A307 Grade 2 fasteners are specified. The 5\/8-11 UNC thread size is a common specification in structural bolt patterns, and the 10-inch length accommodates thicker material stacks or long through-bolt assemblies. The hot-dipped galvanized finish makes it appropriate for exterior and treated-lumber applications where bare steel would corrode prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread size with partial threading along the shank\u003c\/li\u003e\n  \u003cli\u003e10-inch length under head for deep through-bolt assemblies\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish provides corrosion resistance in outdoor and wet environments\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel meets ASTM A307 fastener standard\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with standard hex head drive\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-supply fastener for applications specifying 5\/8-11 UNC hex head bolts to ASTM A307 Grade 2 requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by structural trades, mechanical contractors, or general construction crews using a standard hex wrench, socket set, or impact driver with the appropriate 5\/8-inch drive. Always confirm the mating nut and washer specification matches the Grade 2 ASTM A307 designation before installation. When used with pressure-treated lumber, verify that the hot-dipped galvanized coating meets applicable building code requirements for contact with treated wood. Do not use an impact wrench to overtighten Grade 2 hardware, as this grade has lower proof load limits than Grade 5 or Grade 8 fasteners.\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: 10 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: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Hot-Dipped Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A307\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 pound\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: HCI20621000G6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720705540402,"sku":"HCI20621000G6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0dfea12a67f9e7af79d127fa0a751249.jpg?v=1788567982","url":"https:\/\/voomisupply.com\/products\/value-collection-hci20621000g6-hex-head-bolt-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
