It features a 1-8 UNC (Unified National Coarse) thread pattern with a 5-inch length under head and partial threading along the shank. Manufactured from steel with a hot-dipped galvanized finish, this bolt provides corrosion resistance suitable for outdoor, wet, or exposed environments. It conforms to ASTM A307 standards, making it appropriate for low-carbon steel bolting in structural connections where high-strength fasteners are not required. Weight is approximately 1 pound per unit.\u003c\/p\u003e\n\u003cp\u003eThis bolt is commonly used in construction, general fabrication, agricultural equipment, framing connections, and utility installations. The hot-dipped galvanized coating makes it well suited for exterior structural applications, treated-lumber connections, and other corrosive environments. The partial thread configuration provides a smooth shank section, which is useful in applications requiring shear strength or precise hole alignment. Licensed tradespeople in construction, plumbing, electrical, and HVAC trades routinely use fasteners of this type when assembling equipment supports, pipe hangers, equipment bases, and structural brackets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread size for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e5-inch length under head suits medium-to-deep fastening applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides shear strength and improved hole alignment\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish delivers corrosion resistance for outdoor and exposed use\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A307 standard for low-carbon steel bolting\u003c\/li\u003e\n  \u003cli\u003eGrade 2 classification appropriate for general-purpose, non-critical structural connections\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 compatible with standard 1-8 UNC nuts, washers, and tapped steel or structural components conforming to inch-standard fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should follow applicable structural or mechanical codes for the specific application, such as the IBC or AISC guidelines for structural bolting. Always use an appropriate flat washer and hex nut rated for Grade 2 or higher service. Inspect threads for damage before installation and ensure mating surfaces are clean and properly aligned. Do not use impact tools at torque settings that exceed the rated capacity for Grade 2 fasteners, as over-torquing can cause thread stripping or shank failure.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading Style\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: 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\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161614\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: HCI21000500G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692823314738,"sku":"HCI21000500G","price":18.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58cc862c56f828e9a02abaa576a25267.jpg?v=1788303523","url":"https:\/\/voomisupply.com\/products\/value-collection-hci21000500g-hex-head-bolt-1-8-5in-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
