What are wooden peg pins commonly referred to as?

Wooden peg pins are commonly referred to as trunnels, which is derived from a blend of the words "tree" and "tunnel," reflecting their natural wooden construction and use in structural integrity. Trunnels are primarily used in woodworking and construction to join pieces of wood together, especially in traditional timber framing, providing a sturdy connection that can withstand significant loads.

The term is widely recognized in shipbuilding and historical architecture, where these wooden pegs facilitate strong joints without the need for metal fasteners, which could corrode. Understanding this terminology is crucial for anyone involved in fire inspection or building safety, as it helps in assessing structural integrity and identifying potential fire hazards associated with various building materials and methods.
