It features a 3\/8-16 UNC thread size with a 4-inch length measured under the head and a square neck that locks into place to prevent rotation during tightening. Manufactured from Grade 1006-1050 steel with a galvanized zinc-plated finish, this bolt resists corrosion in moderate-exposure environments. It conforms to ASME B18.5 standards, making it suitable for installations where code-compliant fasteners are required. Licensed tradespeople and general contractors rely on this bolt type for wood framing, equipment mounting, and structural assembly work.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is used across residential and light commercial construction and maintenance applications. Common uses include attaching wood members to metal brackets, securing playground equipment, anchoring structural lumber, and general through-bolt assembly where a clean, round-head profile is needed on the exposed face. The square neck embeds into wood or soft material substrates to resist spinning without a secondary wrench on the bolt end.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head for thick-member fastening applications\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the entire shank length\u003c\/li\u003e\n  \u003cli\u003eSquare neck design locks against substrate to prevent rotation during nut installation\u003c\/li\u003e\n  \u003cli\u003eGalvanized zinc-plated finish for corrosion resistance in moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.5 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.5 inch-series carriage bolt for use with 3\/8-16 UNC nuts and washers in wood, composite, and light-metal through-bolt assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by carpenters, ironworkers, or general tradespeople using a standard wrench or socket on the nut side. Insert the bolt through the pre-drilled hole so the square neck seats flush into the substrate before threading the nut. Tighten from the nut end only — do not drive from the bolt head. Follow applicable building codes and structural specifications for torque and fastener spacing requirements.\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\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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Type\u003c\/strong\u003e: Square\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 1006-1050\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 3GBC906C0400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694662811954,"sku":"3GBC906C0400","price":5487.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a69b59563bb5c180af27d2f57a679c72.jpg?v=1788326854","url":"https:\/\/voomisupply.com\/products\/value-collection-3gbc906c0400-carriage-bolt-3-8-16-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
