The ribbed neck beneath the domed head locks into wood or composite materials to prevent rotation during installation without requiring a wrench on the bolt side. Manufactured from Grade 5 steel with a clear zinc chromate finish for moderate corrosion resistance, this bolt meets SAE J429 standards and carries a 1-inch length under the head with 0.438 inches of thread engagement at the UNC thread standard.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is suited for residential and light commercial construction, woodworking, fencing, decking, and general structural assembly where a smooth-faced fastener head is required on the finished or visible side of the joint. The partially threaded shank and ribbed neck make it particularly effective in wood-to-wood and wood-to-metal connections where spin-out resistance is critical. A nut and washer are applied from the opposing side to complete the joint.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRibbed neck design resists bolt rotation without tooling on the head side\u003c\/li\u003e\n\u003cli\u003eGrade 5 steel construction per SAE J429 for reliable tensile strength\u003c\/li\u003e\n\u003cli\u003eClear zinc chromate finish provides moderate corrosion protection\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank with 0.438 inches of UNC thread length\u003c\/li\u003e\n\u003cli\u003e1-inch length under head suits standard structural panel and lumber thicknesses\u003c\/li\u003e\n\u003cli\u003eInch measurement system with 3\/8-16 UNC thread size for compatibility with standard nuts and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC-threaded carriage bolt for use with 3\/8-16 nuts and washers in wood, composite, and light metal fastening applications conforming to SAE J429 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, general contractors, or maintenance tradespeople using a hammer to seat the ribbed neck flush into the substrate, followed by a standard wrench or socket on the nut side. Always drill a correctly sized pilot hole through the mating materials before driving the bolt. Do not over-torque the nut against soft wood substrates, as this may pull the head through the material. Consult applicable building codes for structural fastener requirements specific to your application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.438 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\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 Coating\u003c\/strong\u003e: Clear Zinc Chromate\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: 0.0136 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161603\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 219204MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700296778034,"sku":"219204MSC","price":12243.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4684f35dcfbb14e7700ba7eb86a595c8.jpg?v=1788388651","url":"https:\/\/voomisupply.com\/products\/value-collection-219204msc-carriage-bolt-3-8-16-1-in-ribbed-neck","provider":"Voomi Supply","version":"1.0","type":"link"}
