It features a square neck design that locks into wood or soft materials during installation, preventing rotation as the nut is driven. The bolt is fully threaded along the shank and carries an uncoated, bright finish. Conforming to SAE J429 fastener standards, it is suited for high-strength structural and mechanical assembly applications. Licensed trades and industrial maintenance professionals use this bolt where tensile strength and secure seating are required.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is appropriate for residential framing, equipment mounting, and light structural connections where a flush, round-head fastener is preferred. The square neck beneath the head prevents spin-out in wood and composite substrates without requiring a wrench on the bolt head. Its Grade 8 alloy steel construction makes it a reliable choice in demanding mechanical assemblies where standard low-carbon fasteners are insufficient.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 alloy steel for high tensile strength in structural and mechanical applications\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 design prevents rotation during nut tightening without a secondary tool\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for standard indoor or protected installations\u003c\/li\u003e\n\u003cli\u003eConforms to SAE J429 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC carriage bolt for use with 5\/16-18 compatible nuts and washers in wood, metal, and composite assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, millwrights, or maintenance technicians using a standard wrench or socket on the mating nut. Seat the square neck fully into the substrate before applying torque to prevent the head from spinning. Follow applicable structural or mechanical assembly codes for proper fastener selection and loading. Inspect for material compatibility before use in corrosive or outdoor environments, as this bolt carries no protective coating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Fully Threaded\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: Bright\/Uncoated\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 215298MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691083301170,"sku":"215298MSC","price":1396.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94ee77dad00547d98ed0becb32696267_c2a916bc-0d6a-4b56-ac75-db05ec63b4d3.jpg?v=1788280142","url":"https:\/\/voomisupply.com\/products\/value-collection-215298msc-carriage-bolt-5-16-18-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
