Truss connector plate

They are produced by punching light gauge galvanized steel to create teeth on one side.

Metal connector plates are manufactured with varying length, width and thickness (or gauge) and are designed to laterally transmit loads in wood.

However, not all types of nail plates are approved for use in trusses and other structurally critical placements.
