The square neck design below the domed head locks into place in a mating square hole or wood substrate, preventing the fastener from rotating during nut tightening without requiring a wrench on the bolt head. The UNC thread form ensures broad compatibility with standard inch-series nuts and tapped holes. This bolt is suited for general mechanical assembly, woodworking, and light structural connections where corrosion resistance is a priority.\u003c\/p\u003e\n\u003cp\u003eCarriage bolts of this size are commonly used in residential and light commercial construction, deck framing, fence assembly, and equipment mounting applications. The 18-8 stainless steel construction makes this fastener a practical choice in outdoor, wet, or mildly corrosive environments where carbon steel hardware would degrade. Licensed contractors, millwrights, and maintenance technicians use fasteners of this type when code or project specifications call for corrosion-resistant hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread form for compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length under head for precise grip-length specification\u003c\/li\u003e\n  \u003cli\u003eSquare neck below head prevents rotation during installation\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in outdoor and wet environments\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating thickness to account for in tight-tolerance assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC inch-series carriage bolt compatible with 1\/4-20 hex nuts, wing nuts, and washers conforming to standard inch-series fastener dimensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a correctly sized square or round hole drilled through the mating material so the square neck seats flush and resists turning. Tighten from the nut side using an appropriate wrench or socket; no tool is applied to the domed head. Follow applicable building codes and project specifications for torque requirements and fastener spacing. Always verify the fastener material is appropriate for the service environment before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 1-1\/4 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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: R63644851\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718258491698,"sku":"R63644851","price":1016.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a96860ade6bfd256eb23dd3940b96bbb.jpg?v=1788551266","url":"https:\/\/voomisupply.com\/products\/value-collection-r63644851-carriage-bolt-1-4-20-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
