Manufactured from Grade 2 steel with a zinc-plated finish, this fastener is built for general-purpose structural and mechanical applications. The square neck seats into the mating material to resist rotation during installation, eliminating the need for a wrench on the bolt head. It meets ASTM A307 standards, making it suitable for low-carbon steel fastener applications across a wide range of trade and construction uses.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is commonly used in wood-to-wood, wood-to-metal, and light structural connections found in residential and commercial construction, HVAC equipment mounting, electrical enclosure fabrication, and general mechanical assembly. The 8-inch under-head length accommodates thicker material stacks or applications requiring extended reach through multiple layers. Installers in carpentry, ironwork, and general mechanical trades will find this bolt a standard fit for everyday fastening tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread form for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e8 inches length under head for extended reach through thick material assemblies\u003c\/li\u003e\n  \u003cli\u003eStandard square neck prevents bolt rotation during nut tightening\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ASTM A307 specifications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance for indoor and sheltered applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC carriage bolt suitable for use with any 3\/8-16 hex nut or coupling nut in general structural and mechanical fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by carpenters, ironworkers, or general mechanical contractors using a standard socket or open-end wrench on the nut side. Insert the bolt through the pre-drilled hole so the square neck seats fully into the material before applying the nut. Tighten from the nut side only — applying torque to the domed head will not drive the fastener. Verify hole diameter and material thickness are appropriate for the 3\/8-inch shank before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Style\u003c\/strong\u003e: Standard Square Neck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Grade 2 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A307\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: R50000271\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693698384178,"sku":"R50000271","price":6728.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b44c29dcd384cab213a44715e086643a.jpg?v=1788316253","url":"https:\/\/voomisupply.com\/products\/value-collection-r50000271-carriage-bolt-3-8-16-unc-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
