A spigot joint is a type of pipe fitting that is inserted into another pipe fitting. The spigot end typically has the same outer diameter as the pipe and is usually fitted into another larger-diameter joint called a bell. Together, these two elements form what is commonly known as a bell and spigot.

Specification
The joint pin or spigot is inserted into the end of the scaffold tubes and a centre bolt is tightened. This tightening causes the two parts of the joint pin to expand gripping the ends of the scaffold tubes.
