Fastener Capscrew 1/2-13X4 1/2

This is a Grade 5 steel dowel bolt, featuring a 1/2"-13 UNC thread and an overall length of 4 1/2 inches. It is specifically designed for use on the inspection hatch of concrete mixer drums. The prominent tapered, unthreaded tip acts as a guide pin, ensuring the heavy hatch cover is correctly aligned before the remaining fasteners are installed. This part is essential for maintenance and is replaced when bent, damaged, or lost during routine drum inspections. The zinc plating provides corrosion resistance in the harsh environment of concrete mixing.
