Toenailing

Toenailing or skew-nailing is a viable, structurally sound method^[1] of the driving of a nail at a roughly 30°^[2] angle to fasten two pieces of wood together, typically with their grains perpendicular. The term comes colloquially from fastening wood at the bottom, or toe, of the board. A variation of toenailing is to use screws, casually known as "toe-screwing". Toenails are typically driven in opposing pairs when possible, or pairs of pairs when appropriate. The angled nailing makes later dismantling difficult or destructive.
