Carriage bolts feature a domed head and a square neck that seats into the material being fastened, preventing rotation during tightening without requiring a wrench on the bolt head. This bolt uses Unified National Coarse (UNC) thread standards and is sized for heavy-duty structural and mechanical fastening applications. The zinc plating provides a baseline level of corrosion resistance suitable for general indoor and sheltered outdoor use. Tradespeople across construction, mechanical, and maintenance trades rely on this bolt style for wood-to-metal and structural assembly work.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is suited for structural connections in wood framing, equipment mounting, and general mechanical assemblies where a flush or recessed fastener head is needed on one face of the joint. The square neck design locks into wood or pre-punched square holes in metal, allowing a nut to be driven from the opposite side without holding the bolt. It is an appropriate choice for decks, framing hardware, HVAC equipment bases, and general fabrication work requiring a 3\/4-inch fastener.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-10 UNC thread for broad nut and hardware compatibility\u003c\/li\u003e\n\u003cli\u003e6-inch length under head accommodates thick material stacks\u003c\/li\u003e\n\u003cli\u003eSquare neck resists rotation during installation without a backup tool on the bolt head\u003c\/li\u003e\n\u003cli\u003eGrade 5 steel provides medium-high tensile strength for structural fastening\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish offers baseline corrosion resistance for general-purpose use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC 3\/4-10 carriage bolt compatible with any 3\/4-10 hex nut, coupling nut, or threaded insert conforming to Unified National Coarse thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by driving the bolt through a pre-drilled hole sized to the shank diameter so the square neck seats flush and locks against rotation. A standard wrench or socket is used to tighten the nut from the opposite side. Always drill clearance holes to the correct diameter to ensure proper square-neck seating. Follow applicable structural and building codes when using carriage bolts in load-bearing connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 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\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: 32175\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714382758194,"sku":"32175","price":94.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7ccc9e8a023adc805b3b5237f35aae3.jpg?v=1788500636","url":"https:\/\/voomisupply.com\/products\/value-collection-32175-carriage-bolt-3-4-10-6-in-grade-5","provider":"Voomi Supply","version":"1.0","type":"link"}
