Made in the USA by W.H. Maze Company, these hardened steel masonry nails drive into concrete, brick, block, and mortar joints without bending. The fluted shank twists as it's driven to lock the nail into the material for strong holding power, and the flat head sits flush against furring strips, framing, and trim.
