The square neck below the domed head locks into a mating hole in wood or sheet metal, preventing rotation during assembly without requiring a tool on the bolt end. Fully threaded along its entire 1-1\/2 inch shank, this fastener delivers consistent clamping force from head to nut. Grade 8 material provides high tensile strength for demanding structural and mechanical applications. The bright uncoated finish meets SAE J429 standards.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for structural assemblies, equipment mounting, and mechanical connections where high-strength fastening is required. Typical applications include fabrication, machinery frames, brackets, and heavy-duty wood-to-metal connections in both residential and light commercial settings. The 3\/8-16 thread size is a common inch-series dimension used across a wide range of industrial and construction fastener applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC fully threaded shank, 1-1\/2 inches length under head\u003c\/li\u003e\n  \u003cli\u003eSquare neck design prevents rotation during tightening\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup on threads\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J429 fastener standard\u003c\/li\u003e\n  \u003cli\u003eInch system dimensions for compatibility with standard inch-series hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/8-16 UNC inch-series nuts and hardware in structural, fabrication, and mechanical fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, fabricators, or general contractors depending on the application. Before installation, ensure the through-hole matches the bolt diameter and the square neck recess is properly formed to prevent spinning. A standard wrench or socket is applied to the nut side only — no tool is needed on the bolt head. Always torque to the value specified by your assembly engineer or applicable structural standard for Grade 8 fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: Grade 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: 0.06 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 215498MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717910724914,"sku":"215498MSC","price":946.34,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94ee77dad00547d98ed0becb32696267_47d92697-ada8-4a2e-9655-bbbe2e5eb4d3.jpg?v=1788547398","url":"https:\/\/voomisupply.com\/products\/value-collection-215498msc-carriage-bolt-3-8-16-1-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
