The square neck seats into mating material to prevent the bolt from spinning during nut installation, eliminating the need for a wrench on the bolt head. At 3 inches in length under the head, it provides adequate thread engagement for typical structural and assembly connections. Manufactured from Grade 5 steel with a zinc-plated finish, it offers a solid combination of tensile strength and basic corrosion resistance suitable for indoor and light-duty outdoor use. Licensed trades and experienced DIYers rely on this bolt size across a wide range of construction and equipment assembly tasks.\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, HVAC equipment mounting, electrical enclosure assembly, and general fabrication. The 1\/4-20 UNC thread is one of the most common inch-series thread specifications, making compatible nuts and hardware widely available. The zinc finish is appropriate for dry or low-moisture environments. Minimum order quantity is 100 pieces, making this bolt well-suited for contractors and shops that require bulk fastener stock.\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\u003e3-inch length under head for adequate thread engagement in thicker assemblies\u003c\/li\u003e\n  \u003cli\u003eSquare neck prevents rotation during installation without a second tool on the bolt\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction provides reliable tensile strength for structural fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish delivers basic corrosion resistance in dry and low-moisture environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC inch-series carriage bolt compatible with 1\/4-20 hex nuts, wing nuts, and washers conforming to ANSI inch fastener standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCarriage bolts are typically installed by tradespeople and maintenance technicians using standard hand tools. Insert the bolt through the pre-drilled hole so the square neck seats fully and flush into the mating material before applying the nut. Do not overtighten beyond the rated proof load of Grade 5 fasteners. Fastener installations in structural or load-bearing applications should comply with applicable building codes and engineering specifications.\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: 3 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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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: 0.0835 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 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: 32159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689189736754,"sku":"32159","price":6773.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/006fa3d4710c258746963c5c74db62e1.jpg?v=1788255904","url":"https:\/\/voomisupply.com\/products\/value-collection-32159-carriage-bolt-1-4-20-3-inch-grade-5","provider":"Voomi Supply","version":"1.0","type":"link"}
