Made from Grade 2 steel with a zinc-plated finish, this bolt is designed to resist corrosion in general-purpose fastening applications. The square neck seats into a pre-drilled hole to prevent rotation during tightening, allowing the nut to be driven from one side without holding the bolt head. It meets ASTM A307 standards and suits a wide range of structural and light mechanical assemblies. This type of fastener is commonly installed by contractors, maintenance technicians, and trade professionals working on wood, metal, or composite structures.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for residential and light commercial construction, woodworking assemblies, fence and deck framing, and general equipment mounting. The 1\/4-20 UNC thread pattern is one of the most common fractional thread sizes in inch-standard fastening, making compatible nuts and washers widely available. The zinc coating provides a baseline level of corrosion resistance appropriate for dry or semi-protected interior and exterior environments. Sold individually with a minimum order quantity of 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e4.5-inch length under head suits medium-depth through-bolt applications\u003c\/li\u003e\n  \u003cli\u003eSquare neck prevents bolt rotation during installation without tool access to the head\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ASTM A307 fastener standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for compatibility with standard fractional tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose inch-standard carriage bolt compatible with standard 1\/4-20 UNC hex nuts and washers.

Drill a hole sized to the bolt shank diameter so the square neck seats flush and locks against rotation. Thread a compatible 1\/4-20 nut onto the exposed end and tighten to the assembly specification using an appropriate wrench or socket. Do not apply torque to the domed head, as it is not designed for tool engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 4.5 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 489033PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718081708338,"sku":"489033PS","price":2906.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29e152f0299c34fe0927906117427ffb.jpg?v=1788549331","url":"https:\/\/voomisupply.com\/products\/value-collection-489033ps-carriage-bolt-1-4-20-4-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
