This listing is for four pieces. The DW weld screw is designed with a long, narrow spade at right angles
to the thread and a single button weld projection. The DW weld screw is
particularly suitable for use in narrow channels, confined areas and
corners. It can also be used in applications where threads must be
offset from the surface. The DW weld screw is easy to locate and it
produces a strong, sound weld.
