It features a 5\/16-18 UNC thread at 1-1\/2 inches length under head and is fully threaded along its entire shank. The square neck under the domed head prevents rotation during installation, eliminating the need for a wrench on the bolt side. A zinc trivalent chromate finish provides corrosion resistance in standard service environments. This fastener meets SAE J429 standards and is suited for use by maintenance technicians, millwrights, fabricators, and general tradespeople working with structural or mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is appropriate for residential and light commercial construction, equipment fabrication, and mechanical assembly applications where a flush, rounded head profile is required. The fully threaded design maximizes engagement across the full shank length, making it well suited for thinner material stacks. It is measured in the inch system and conforms to UNC thread standards, ensuring compatibility with standard SAE nuts and hardware commonly stocked in trade environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC fully threaded shank, 1-1\/2 inches length under head\u003c\/li\u003e\n  \u003cli\u003eSquare neck under head prevents bolt rotation without a secondary tool\u003c\/li\u003e\n  \u003cli\u003eZinc trivalent chromate finish for corrosion protection\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J429 fastener standard\u003c\/li\u003e\n  \u003cli\u003eInch system measurement; compatible with standard SAE hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5\/16-18 UNC SAE nuts and washers in structural, mechanical, and general fabrication assemblies requiring a Grade 8 alloy steel carriage bolt.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by maintenance technicians, fabricators, or general tradespeople using standard SAE hand tools. Insert the bolt through a pre-drilled clearance hole so the square neck seats fully into the material to prevent rotation, then thread and torque the nut from the opposite side. Always ensure hole diameter matches the bolt shank to allow the square neck to seat correctly. Follow applicable structural or mechanical codes for proper torque and joint specifications.\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\u003eThread Style\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/2 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: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Trivalent Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: SAE J429\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: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8 inches L x 6 inches W x 0.75 inches H\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: 215297MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696132555058,"sku":"215297MSC","price":1427.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94ee77dad00547d98ed0becb32696267_8a51ef74-32d9-477f-84b1-bef80217e5ee.jpg?v=1788340185","url":"https:\/\/voomisupply.com\/products\/value-collection-215297msc-carriage-bolt-5-16-18-1-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
