•*The"Shakeproof"Threadcuttingscrew
actually cuts its own standard machine
screw thread from a drilled hole, and can
be used again, or can be replaced, if
necessary, by an ordinary machine screw
of the same size. Assembly time is
speeded up . . . and the cost of tapping
eliminated. A snug tight-fitting fastening
is ensured. It drives easily in almost any
metal . . . steel, aluminium and alloys,
iron, copper or brass. Its use is specially
recommended in aircraft manufacture for
securely joining together materials of any
thickness, in secondary structures in
particular, giving increased production
and efficiency.
