It is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance for general-purpose fastening applications. The square neck seats into the material during installation to prevent the bolt from spinning as the nut is tightened. This fastener meets ASTM A307 standards and is sized in the inch measurement system. It is commonly installed by tradespeople and maintenance technicians in light structural, mechanical, and equipment-mounting applications.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for wood-to-wood and wood-to-metal connections in residential and light commercial construction, as well as general maintenance and equipment assembly. The 5\/16-18 thread size is widely used in framing, rail, fence, and panel-mounting work where a smooth, round head on the bearing side is required. The zinc plating offers surface protection in dry to mildly humid indoor environments. This fastener is sold in multiples of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread size for broad compatibility with standard inch-system hardware\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003eSquare neck locks into substrate to prevent rotation during nut tightening\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ASTM A307 fastener standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance in dry and low-humidity environments\u003c\/li\u003e\n  \u003cli\u003eSmooth domed head leaves a clean bearing surface flush against the material face\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-system carriage bolt for use with 5\/16-18 UNC nuts and hardware in general-purpose structural and mechanical fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation typically requires a drill or bit sized to match the bolt shank diameter so the square neck seats properly. Insert the bolt from the through-hole side and tighten the nut from the opposite face using a standard wrench or socket. Do not use impact tools at full torque on Grade 2 hardware, as this grade has lower tensile strength than higher-grade fasteners. Follow applicable building codes and structural requirements for the specific application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\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: 2-1\/2 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 2\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\u003eMeasurement System\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\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: R50000188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715017179442,"sku":"R50000188","price":16543.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6169f73485f10bb88e419764e16296a8.jpg?v=1788508831","url":"https:\/\/voomisupply.com\/products\/value-collection-r50000188-carriage-bolt-5-16-18-2-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
