It is a type retaining fastener in mechanical engineering. For instance a gudgeon pin attaches a piston to a connecting rod in an engine.
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").

I believe a gudgeon pin is what the British call a connecting rod pin (or wrist pin or piston pin) in a reciprocating assembly, (piston, connecting rod, crank ) It connects the piston head to the connecting rod.
The gudgeon pin or wrist pin (as it is called in the US), connects the piston to the connecting rod and provides a bearing for the connecting rod to pivot upon as the piston moves.

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.
The size of a pin head is roughly two mm in diameter. The size of a sewing needle head is roughly five mm in diameter.
A standard push pin is approximately 2mm in size.
