Abstract

1506938 Wood screws YOSHIDA KOGYO KK 7 April 1975 [26 April 1974] 14115/75 Heading F2H [Also in Division B3] The neck portion 14 of a wood screw between its head 12 and thread 13 is provided with at least one flat crested annular collar 15 extending in a plane at right-angles to the longitudinal axis of the screw and whose outer diameter is approximately equal to the major thread diameter, the collar 15 preventing loosening of the screw and sealing between the screw and wood into which the screw is driven.
