Isaac Kremer/ September 9, 2018/ / 0 comments
A slightly conical pin, peg, or trenail of hard wood, driven through the cheeks of a mortise and tenon inserted therein; the hole in the tenon being slightly farther from the end than those in the mortise, the pin draws the tenon with great force into its seat and secures it firmly. Called also draw pin. (Sturgis, 1900)
