Abstract
A hanger adapted to be driven into a wooden frame member includes a one-piece stamped metal member having a head and a flat elongate symmetrical shank with a series of lands and grooves disposed on opposite sides of the longitudinal axis of the shank between its tip and a pair of laterally extending shoulders on its head. Inclined camming surfaces extend between the lands and grooves and cooperate therewith to compress the wood fibers laterally of the shank as it is driven into the wood. A lateral gripping surface behind each land surface engages the wood fibers which expand into the distally adjacent groove to provide a positive gripping action which resists disengagement.
