Constructed from Grade 18-8 stainless steel with an uncoated finish, this fastener provides reliable corrosion resistance in wet or outdoor environments. The square neck locks into place in a mating hole to prevent rotation during assembly, allowing a nut to be tightened from one side without holding the bolt head. This style is a standard choice for trade professionals and maintenance technicians working with wood, composite, or thin metal assemblies where a smooth, rounded head is required on the finished face.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for general fastening applications across HVAC equipment panels, pool equipment enclosures, electrical boxes, and structural support assemblies. The 1\/4-20 UNC thread is one of the most common imperial thread standards, making this bolt broadly compatible with standard hex nuts, wing nuts, and washers of the same thread specification. The uncoated 18-8 stainless steel construction makes it appropriate for both indoor and outdoor service environments where mild to moderate corrosive exposure is present.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard inch-system hardware\u003c\/li\u003e\n  \u003cli\u003e0.5 inch length under head for compact fastening applications\u003c\/li\u003e\n  \u003cli\u003eSquare neck prevents bolt rotation during nut tightening without a wrench on the head\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 stainless steel construction provides corrosion resistance in wet and outdoor conditions\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no plating to chip, flake, or react with dissimilar metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use carriage bolt compatible with any application requiring a 1\/4-20 UNC square neck carriage bolt with a 0.5 inch length under head in inch-system fastener hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by maintenance technicians, electricians, HVAC installers, or plumbers as part of equipment mounting or structural assembly work. Drill or punch the mating hole to the correct diameter so the square neck seats firmly and resists rotation before applying the nut. Use a properly sized wrench or socket on the nut side and tighten to the specification required by the assembly drawing or equipment manufacturer. Avoid overtightening into soft materials such as wood or thin-gauge sheet metal to prevent stripping or deforming the mating surface.\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: 0.5 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: Grade 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: 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: R63644686\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708071969074,"sku":"R63644686","price":3844.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b37d850090bd19c48945107aaab43197.jpg?v=1788443875","url":"https:\/\/voomisupply.com\/products\/value-collection-r63644686-carriage-bolt-1-4-20-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
