It features a 1\/2-13 UNC thread size with a fully threaded shank measuring 5-1\/2 inches under the head, and a square neck below the domed head that locks into wood or soft material to prevent rotation during installation. The uncoated bright finish is standard for structural and mechanical assemblies where a coating is not required. Fasteners at this grade and thread size are typically installed by millwrights, structural ironworkers, agricultural equipment technicians, and general contractors working on heavy-duty connections.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for residential and commercial structural assemblies, agricultural equipment, timber framing, machinery mounting, and other applications requiring a reliable high-strength fastener conforming to SAE J429 standards. The fully threaded configuration allows maximum thread engagement across the full shank length, making it appropriate for through-bolt applications with nuts and washers. Sold in a minimum order quantity of 10 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC fully threaded shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e5-1\/2 inch length measured under the head\u003c\/li\u003e\n  \u003cli\u003eSquare neck below domed head prevents rotation without a wrench on the bolt\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish — no added plating or coating\u003c\/li\u003e\n  \u003cli\u003eConforms to SAE J429 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC carriage bolt for use with 1\/2-13 hex nuts and appropriately sized washers in structural, agricultural, and mechanical assemblies requiring a Grade 8 alloy steel fastener per SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by inserting the bolt through a pre-drilled hole so the square neck seats into the material and prevents rotation, then threading a nut onto the exposed end and tightening with a standard wrench or socket. Power down or de-energize any equipment before installing or removing fasteners on machinery. Follow applicable structural or equipment manufacturer torque specifications for 1\/2-13 Grade 8 fasteners as required by the job specification. Inspect the square neck seating before final torque to confirm the bolt is not spinning freely.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 5-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated \/ Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: SAE J429\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: 0.321 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 pieces\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: 216278MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698520588594,"sku":"216278MSC","price":4772.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/698625eacc56097d3387fc980647b739.jpg?v=1788364164","url":"https:\/\/voomisupply.com\/products\/value-collection-216278msc-carriage-bolt-1-2-13-5-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
