It features a square neck profile that locks into pre-drilled holes in wood or soft materials, preventing rotation during installation without requiring a wrench on the bolt head. The zinc plating provides basic corrosion resistance for interior and light-duty exterior applications. This fastener meets ASTM A307 standards and is sold in a minimum order quantity of 50 pieces, making it appropriate for stocking or batch fastener work on construction and assembly projects.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is used in light structural wood connections, equipment mounting, and general assembly tasks encountered in residential construction, facility maintenance, and trade rough-in work. The 5\/16-18 coarse thread engages standard nuts and threaded hardware readily. The zinc finish suits dry or low-moisture environments. Plumbers, electricians, HVAC techs, and general contractors commonly stock these fasteners for equipment pad mounting, panel bracing, and structural attachment details.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for compatibility with standard nuts and hardware\u003c\/li\u003e\n  \u003cli\u003eSquare neck locks bolt in place during nut tightening without secondary tooling on the bolt head\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ASTM A307 load requirements for light structural use\u003c\/li\u003e\n  \u003cli\u003eZinc plating provides corrosion resistance in dry and low-humidity environments\u003c\/li\u003e\n  \u003cli\u003e1-inch length under head suits thin-panel and light-framing connections\u003c\/li\u003e\n  \u003cli\u003eSold in 50-piece minimum quantity for stocking and batch installation use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5\/16-18 UNC hex nuts and washers in wood-to-wood or wood-to-metal connections where a flush, rotation-resistant bolt head is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed contractor or qualified tradesperson should verify that fastener grade and size meet the load requirements of the specific application before installation. Drill a clean through-hole sized to allow the square neck to seat flush and grip properly. Drive the bolt through the material, seat the square neck into the hole, then apply a washer and nut and tighten with a standard wrench or socket. Do not over-torque; Grade 2 fasteners have lower proof load limits than Grade 5 or Grade 8 hardware.\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: 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 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\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces minimum order\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: CAI203101000-050B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720875802930,"sku":"CAI203101000-050B","price":16.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8438330f7945bfe321e77fc490c60eb.jpg?v=1788570354","url":"https:\/\/voomisupply.com\/products\/value-collection-cai203101000-050b-carriage-bolt-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
