The square neck below the dome head locks into wood or structural material to prevent rotation during installation, eliminating the need for a second wrench on the fastener. This bolt conforms to ASTM A307 standards, making it a straightforward choice for general-purpose structural assembly. Trade professionals and contractors reach for this fastener in framing, decking, equipment mounting, and utility connections where a smooth, rounded head profile is required.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is suited for through-bolt applications in wood-to-wood and wood-to-metal connections across residential construction, light commercial framing, and general fabrication work. The 1\/2-13 UNC thread pitch is a common coarse-thread specification that pairs with standard hex nuts and washers available at any trade supply. The zinc plating provides a baseline level of corrosion resistance for interior and covered exterior installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC coarse thread for compatibility with standard nuts and hardware\u003c\/li\u003e\n\u003cli\u003e12-inch length under head for deep through-bolt applications\u003c\/li\u003e\n\u003cli\u003eSquare neck resists rotation during tightening without tools on the bolt head\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets ASTM A307 fastener standards\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish offers baseline corrosion protection for general use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose carriage bolt for standard 1\/2-13 UNC threaded applications in wood, metal, and composite structural assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, ironworkers, or general tradespeople using a standard socket or open-end wrench on the mating nut. Pull the bolt through the pre-drilled hole so the square neck seats fully into the material before applying a washer and nut on the threaded end. Torque the nut to the project specification rather than driving the bolt head, which is not designed for tool contact. Consult applicable building codes for required fastener schedules in structural applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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: 12 inches\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 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\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: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 489135PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715116433714,"sku":"489135PR","price":1492.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f884452907ec0822f7199563dc9a9de.jpg?v=1788509621","url":"https:\/\/voomisupply.com\/products\/value-collection-489135pr-carriage-bolt-1-2-13-12-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
