What is another word for gudgeon pin?
Pronunciation: [ɡˈʌd͡ʒɒn pˈɪn] (IPA) 
A gudgeon pin is a small cylindrical component that connects the piston to the connecting rod in internal combustion engines. It is also known by several other names, such as wrist pin, piston pin, and floating pin. The term wrist pin comes from its location at the piston's wrist position. Similarly, the term piston pin refers to its role of keeping the piston and connecting rod together.
