The bolt is partially threaded and finished with a hot-dipped galvanized coating for corrosion resistance in outdoor and high-moisture environments. It meets ASTM A307 standards, making it appropriate for general structural and mechanical fastening applications where a low-carbon steel fastener with controlled tensile strength is required. Weighing approximately 1 pound, this fastener is suited for heavy assemblies that demand a long-reach bolt with reliable thread engagement.\u003c\/p\u003e\n\u003cp\u003eThis bolt is commonly used in construction, infrastructure, HVAC equipment mounting, plumbing support structures, and general industrial assembly. It is well suited for connecting heavy timber, steel framing, equipment bases, and structural brackets where a 1-inch diameter, partially threaded fastener with a standard hex head is specified. The hot-dipped galvanized finish makes it appropriate for exterior installations or environments with elevated moisture exposure. Tradespeople including pipefitters, structural ironworkers, HVAC installers, and general contractors regularly use this size in large-scale fastening applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread form — standard coarse thread for general structural use\u003c\/li\u003e\n  \u003cli\u003e18-inch length under head provides extended reach for thick material assemblies\u003c\/li\u003e\n  \u003cli\u003eGrade 2 low-carbon steel construction meets ASTM A307 tensile requirements\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish delivers corrosion resistance for outdoor or wet conditions\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for a stronger bearing surface in wood and structural connections\u003c\/li\u003e\n  \u003cli\u003eHex head design accepts standard wrenches and impact sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Grade 2 hex head bolt for structural and mechanical fastening applications requiring a 1-8 UNC thread, 18-inch length, and hot-dipped galvanized finish per ASTM A307.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with applicable structural fastening standards and torque requirements for the specific assembly. Always verify that the receiving material and nut specification match the Grade 2 ASTM A307 rating before installation. Use appropriate wrenches or impact tools rated for 1-inch fasteners. Do not exceed the rated tensile load for this grade when specifying in load-bearing connections.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 18 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\u003eThread Standard\u003c\/strong\u003e: UNC\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: HCI21001800G6-001BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707187102002,"sku":"HCI21001800G6-001BX","price":32.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3120631e28fdd3e22d6f86c4d799728.jpg?v=1788438823","url":"https:\/\/voomisupply.com\/products\/value-collection-hci21001800g6-001bx-hex-head-bolt-18in-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
