The square neck design locks the bolt in place against the material surface during installation, preventing rotation as the nut is tightened. This bolt meets ASTM A307 fastener standards, making it a dependable choice for general-purpose structural and mechanical assembly work. Installation is performed by tradespeople across construction, fabrication, and mechanical maintenance applications where a smooth, round head profile and anti-rotation neck are required.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for wood-to-wood, wood-to-metal, and light structural connections in residential and commercial construction, equipment mounting, and general fabrication. The zinc plating provides basic corrosion resistance for indoor and dry outdoor environments. The 1\/2-13 UNC thread size is a common inch-series specification, compatible with standard 1\/2-13 hex nuts and washers. Sold individually; minimum order quantity is 25 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread size for compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003e7.5-inch length under head for applications requiring extended fastener reach\u003c\/li\u003e\n  \u003cli\u003eSquare neck design prevents bolt rotation during nut tightening without requiring a wrench on the head\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ASTM A307 fastener standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion resistance for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eSmooth domed head provides a clean, flush appearance on the exposed face\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC hex nuts and flat washers in general-purpose structural and mechanical fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation typically requires a standard wrench or socket to drive the nut while the square neck seats into the material and holds the bolt stationary. Always pre-drill a clean hole sized to the bolt shank diameter to allow the square neck to seat properly. For structural applications, consult applicable building codes and load requirements before specifying fastener grade. Inspect zinc plating for damage before use in corrosion-sensitive environments.\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: 7.5 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  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 489128PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698526486834,"sku":"489128PR","price":4988.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/284cfff572d83317f8705787d3a08f0a.jpg?v=1788364233","url":"https:\/\/voomisupply.com\/products\/value-collection-489128pr-carriage-bolt-1-2-13-7-5-in-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
