What are wooden peg pins called?

• A. Trunnels
• B. Dowel pins
• C. Quick-set nails
• D. Wrought iron pins

Answer: (A)

Wooden peg pins used to join timber in traditional framing and shipbuilding are called trunnels. These are cylindrical wooden pegs driven through aligned holes to lock two or more timbers together. The wood swells with moisture and friction helps keep the joint tight, providing a strong connection without metal fasteners. Dowel pins are typically smaller, used for lighter joints like furniture; quick-set nails are metal nails; wrought iron pins are metal fasteners. So the wooden peg pin term that fits is trunnels.
