Manufactured from Grade 2 steel with a zinc-plated finish, it meets ASTM A307 standards for general-purpose structural and mechanical fastening. The round, domed head sits flush against the mating surface while the square neck bites into wood or soft substrates to prevent spinning during nut tightening. This bolt is a standard inch-system fastener used across construction, woodworking, and light structural assembly applications.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for light to medium-duty applications in residential construction, framing, deck building, fence installation, and general fabrication. The 5\/16-18 coarse thread and 6-inch shank length accommodate connections through thicker stock or layered materials. The zinc-plated finish provides a baseline level of corrosion resistance appropriate for interior or covered exterior use. Trade professionals including carpenters, general contractors, and maintenance technicians commonly use this bolt where through-bolting with a washer and nut is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC coarse thread for reliable engagement in standard tapped holes or with standard hex nuts\u003c\/li\u003e\n\u003cli\u003e6-inch length under head suits connections through thick lumber or stacked material\u003c\/li\u003e\n\u003cli\u003eSquare neck prevents rotation when driven into wood substrates, allowing single-side installation\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets ASTM A307 fastener standard\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides basic corrosion resistance for general indoor and covered applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose inch-system carriage bolt compatible with standard 5\/16-18 UNC hex nuts and washers in wood-to-wood or wood-to-metal fastening applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation typically requires a hammer to seat the square neck flush into the substrate and a wrench or socket to tighten the mating nut. Always use an appropriate flat washer under the nut to prevent pull-through on softer materials. Follow applicable building codes for structural fastener spacing and load requirements. Inspect the zinc finish for damage before installation in damp or outdoor environments where additional corrosion protection may be required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 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 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\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\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: 489061PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716124901682,"sku":"489061PR","price":2905.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a5dff43266ab0caf5cf78dfe9b1d924f.jpg?v=1788522094","url":"https:\/\/voomisupply.com\/products\/value-collection-489061pr-carriage-bolt-5-16-18-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
