It is a type retaining fastener in mechanical engineering. For instance a gudgeon pin attaches a piston to a connecting rod in an engine.
Gudgeon Pin/Piston Pin
A gudgeon is a small freshwater fish. A gudgeon pin is a small rod which connects the piston to the connecting rod in an internal combustion engine (often shortened to "gudgeon").

Broaches are used in machining metal. They are used by almost every industry that makes machined metal parts. jewelry business, a broach is a pin
crnke shaft is the one which is attached with piston trough gudgeon pin or swift pin. Its main use is to rotate the piston in rotary motion with the help of counter weight,due to which piston resiprocate up and down.
