TYPES AND USES - Continued
RADIO AND POCKET SCREWDRIVERS
A radio screwdriver (1) has a round blade that is 1-1/2
inches long. Its use is restricted to very small screws
generally used in the construction of radio chassis. The
pocket screwdriver (2) is also small, with a square blade
that is 1-3/4 inches long. Both have pocket clips.
SCREW STARTER OR GIMLET
A screw starter or gimlet has a threaded tip. It is used to
make a pilot hole in wood for wood screws.
The proper way to select and use a
screwdriver is to always match the
size of the screwdriver to the job and
always match the type of screwdriver
to the head of the screw.
