This high-strength fastener is a Grade 8 hex head cap screw designed for heavy-duty applications in concrete mixers and other heavy machinery. With dimensions of 7/8"-14 x 4.5", it is manufactured from heat-treated medium carbon alloy steel to meet or exceed SAE J429 Grade 8 specifications, providing superior tensile strength for high-stress connections. The yellow zinc plating offers robust protection against corrosion, making it an essential replacement part for securing critical components like pedestals and mounting frames on equipment exposed to the elements.
