Oak trenails that will be used to pin a wooden structure together. The one in the front has been used and pulled out, showing the way forces have permanently deformed the wood.

A treenail, also trenail, trennel, or trunnel, is a wooden peg, pin, or dowel used to fasten pieces of wood together, especially in timber frames, covered bridges, wooden shipbuilding and boat building.[1] It is driven into a hole bored through two (or more) pieces of structural wood (mortise and tenon).
