When compressed into timber by a bolt and nut, a conical spring washer's coils compact into each other until the entire form is flat. The tapered design of the washer maintains a constant pressure on the bolt and the timber ensuring any shrinkage of the timber over time won't affect the torque of the bolt or compromise the connection.
