It features a ribbed neck under the domed head that bites into the mating material to prevent rotation during installation, eliminating the need for a wrench on the bolt end. Manufactured from Grade 5 steel with a zinc-plated clear chromate finish, it provides a balance of tensile strength and corrosion resistance suited to indoor and light-duty outdoor assemblies. The bolt measures 3\/4 inch in length under head with 3\/8 inch of thread, conforming to SAE J429 standards.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is used in wood-to-wood, wood-to-metal, and light structural connections across residential construction, equipment fabrication, and general maintenance work. The partially threaded shank and ribbed neck make it a practical choice for situations where through-bolt installations require a flush, non-turning head on one face. Installers working on framing, brackets, enclosures, and similar assemblies will find this size commonly specified. Sold individually with a minimum order quantity of 100 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRibbed neck prevents bolt rotation without a secondary tool on the head side\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 tensile strength requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated clear chromate finish provides corrosion resistance in dry and light-exposure environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank with 3\/8 inch of UNC thread engagement\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 thread size in the commonly stocked 3\/4 inch under-head length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard SAE J429-compliant 1\/4-20 UNC carriage bolt compatible with any application requiring a 1\/4 inch diameter partially threaded carriage bolt with a ribbed neck and 3\/4 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by driving the bolt through a pre-drilled clearance hole sized for a 1\/4 inch fastener, then seating the ribbed neck into the material so the head sits flush and cannot spin. A standard hex nut and wrench are used to tighten from the threaded end. Follow applicable structural fastening codes and torque guidelines specified by the assembly designer for Grade 5 hardware. Inspect the mating surface to ensure the ribbed neck fully embeds before applying final torque.\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\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Type\u003c\/strong\u003e: Ribbed\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 Clear Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: 0.1 pounds\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: 218874MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694278902066,"sku":"218874MSC","price":3334.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22584a9f2f6a7054a54d28d9344cb23e.jpg?v=1788322524","url":"https:\/\/voomisupply.com\/products\/value-collection-218874msc-carriage-bolt-1-4-20-3-4-in-grade-5","provider":"Voomi Supply","version":"1.0","type":"link"}
