The square neck seats into the material being fastened to prevent the bolt from spinning during installation, eliminating the need for a wrench on the bolt head. Zinc plating provides a baseline level of corrosion resistance suited for general indoor and light-duty applications. This fastener meets ASTM A307 standards and is sized in the inch measurement system. It is a standard trade-supply fastener installed by electricians, plumbers, HVAC technicians, and general contractors across a wide range of construction and equipment-mounting tasks.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for light structural connections, wood-to-wood assemblies, and equipment mounting applications where a smooth, rounded head is required on the bearing surface. The 3\/8-16 UNC thread is one of the most common inch-series thread pitches used in residential and light commercial construction. Typical applications include securing framing members, mounting brackets, and attaching components in mechanical rooms or utility installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for compatibility with standard inch-series nuts and hardware\u003c\/li\u003e\n  \u003cli\u003e1-inch length under head for shallow-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003eSquare neck design prevents bolt rotation during nut tightening without a back wrench\u003c\/li\u003e\n  \u003cli\u003eGrade A steel construction meets ASTM A307 fastener standard\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for basic corrosion resistance in dry or low-moisture environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series carriage bolt compatible with 3\/8-16 UNC nuts, washers, and threaded inserts used in general construction, mechanical, and utility fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard wrench or socket on the mating nut. Ensure the square neck is fully seated into the material to prevent spinning before applying torque to the nut. For structural applications, consult applicable building codes to confirm fastener grade and size requirements. Zinc-plated hardware is not recommended for outdoor or high-moisture environments where a hot-dip galvanized or stainless fastener would be more appropriate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eLength Under Head\u003c\/strong\u003e: 1 inch\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 A\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161603\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: 34626\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716196827442,"sku":"34626","price":25.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d6ce0f671de6c885d0e705f34ee7872.jpg?v=1788523028","url":"https:\/\/voomisupply.com\/products\/value-collection-34626-carriage-bolt-3-8-16-1-in-zinc-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
