These fasteners are designed to secure a wooden face to either a wood or metal frame. The flat head eliminates the need for a washer while providing a semi-flush finish at the surface. The square underside of the head is self-locking, preventing spinning during installation and removing the need for a driving tool on the bolt itself. The galvanized finish delivers reliable rust prevention, though it may present a chalky appearance in some applications.\u003c\/p\u003e\n\u003cp\u003eThese carriage bolts are suited for residential and light commercial construction, woodworking, framing, and general structural fastening where corrosion resistance is required. Common applications include deck construction, fence assembly, outdoor structures, and wood-to-metal connections exposed to moisture. The 100-piece pack quantity supports production work and job-site efficiency for carpenters, general contractors, and trade professionals handling volume fastening tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4 inch diameter by 2.5 inches length for standard structural fastening applications\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish provides corrosion and rust resistance for interior and exterior use\u003c\/li\u003e\n  \u003cli\u003eFlat head design eliminates the need for a washer and delivers a semi-flush surface finish\u003c\/li\u003e\n  \u003cli\u003eSquare underside of head locks into wood to prevent spinning without a driving tool on the bolt\u003c\/li\u003e\n  \u003cli\u003e100-piece pack quantity supports high-volume and production fastening work\u003c\/li\u003e\n  \u003cli\u003eCompatible with wood-to-wood and wood-to-metal frame connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for fastening a wooden face to wood or metal frame assemblies.

Before installation, drill a correctly sized clearance hole through the workpiece so the square neck seats flush and locks without spinning. A nut and wrench are required on the threaded end to draw the joint tight. No driving tool is needed at the bolt head once the square neck is properly seated in the substrate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Flat with square underside neck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Box (BX)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 43.15 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: HILLMAN FASTENERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 812515\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51559407288626,"sku":"812515","price":405.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9aca8f191d19b3273a5ee28d9093e57_52618b18-aed6-461f-b856-dae72b3053ef.jpg?v=1786431489","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-812515-galvanized-carriage-bolt-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
