The square neck beneath the domed head resists rotation during installation, eliminating the need for a wrench on the bolt side. Finished with a clear zinc chromate coating for basic corrosion resistance, this fully threaded fastener meets SAE J429 standards. It is suited for high-strength bolted connections in structural, mechanical, and heavy equipment assemblies where Grade 8 tensile strength is required.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is used in applications that demand a Grade 8 fastener, including farm equipment, trailer frames, utility structures, and heavy-duty framing assemblies. The 1\/2-13 UNC thread is a common size across industrial and construction hardware, making this bolt a standard replacement or new-installation choice for maintenance crews and fabricators working with inch-dimensioned hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile strength and load capacity\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC fully threaded shank, 5 inches length under head\u003c\/li\u003e\n\u003cli\u003eSquare neck locks against material surface to prevent bolt spin during nut tightening\u003c\/li\u003e\n\u003cli\u003eClear zinc chromate finish provides baseline corrosion protection\u003c\/li\u003e\n\u003cli\u003eMeets SAE J429 fastener standard\u003c\/li\u003e\n\u003cli\u003eSold in a package of 10 bolts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series carriage bolt for use with 1\/2-13 UNC hex nuts and corresponding hardware in structural and mechanical assemblies requiring Grade 8 fasteners.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by inserting the bolt through a pre-drilled hole so the square neck seats into the material, preventing rotation. A wrench or socket is applied only to the nut side. Verify the mating nut and any washers are also rated Grade 8 to maintain the integrity of the joint. Follow applicable torque specifications for 1\/2-13 Grade 8 fasteners as defined by the equipment manufacturer or relevant industry standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\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: Clear Zinc Chromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: SAE J429\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.294 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 216257MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694099431730,"sku":"216257MSC","price":11211.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a0dddfc1688360d11d9f2a5ebc8da81.jpg?v=1788320225","url":"https:\/\/voomisupply.com\/products\/value-collection-216257msc-carriage-bolt-1-2-13-5-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
