ase proper
screwdriver
Next to the hammer, the
screwdriver is probably the
most abused item in the home-
owner's tool kit,
It takes the kind of abuse that
frequently results in chewed up
screw heads, damaged screw-
drivers and gashed hands.
The Hand Tools Institute
(HTl), the association for
American and Canadian manu-
facturers, of quality hand tools,
points out that screwdrivers are
available in a wide variety of
shapes, sizes and materials.
However, they all are in-
tended for one simple use: driv-
ing and withdrawing screws.
Unfortunately, says HT1, the
screwdriver is all too frequently'
used for prying, chiseling,
scraping, punching and some-
times even to stir paint!
But perhaps the most com-
mon abuse is using a screw-
driver that does not match or fit
the screw.
The unsafe use of 'a screw-
driver is most often due to the
fact that the homeowner simply
does not have a proper assort-
ment of these tools on hand.
The two basic types of screw-
drivers are the so-called stan-
dard or conventional, which is
used for screws with slotted
heads, and the Phillips, which is
used for screws with recesses in
the head.
Standardscrewdrivers are
usually classified,according to
tip width and blade length. Gen-
erally, the longer the length, the
wider the tip, although some
rather long screwdrivers may
have a narrow tip.
Cabinet style screwdrivers,
for example, have long, straight
sided shanks and narrow tips,
and are useful for driving
screws into recessed and coun-
terbored openings in cabinets
and fine furniture.
There also are short, stubby ,
screwdrivers with wide tips for f
driving screws in confined quar-•'.
ters.
Most screwdriver tips are ta-
pered. The, tip thickness deter-
mines the size of the screw that
can be driven without damaging
the screw slot. The taper per-
mits the screwdriver to drive
more than one size of screw.
Heavy-duty screwdrivers are
available with square shanks so
that a wrench can be used on the
shank for extra turning power.
As a rule, the bigger the screw-
driver, the larger the diameter of
the handle; the larger the diame-
ter of the handle, the greater the
torque, or turning power.
If •absolutely necessary, a
wrench—but never pliers—can
be used on the shank to apply
the extra torque required.
In the right and safe way .of.'
using a screwdriver, the first
move is to make a pilot hole be-
fore driving a screw. This is es-
pecially important when driving
into hardwood or when the
screw is near the edge of a
board.
Pilot holes can be, made in
softwoods, and in some hard-
woods, with an awl—if the
screws to be used are small.
For larger screws, it is best
to drill a pilot hole or use a
threaded screw hole starter.
If the screw is a flathead, the
pilot hole also should be coun-
tersunk so the head of the screw
will be flush with the work
when it is driven home.
The job of driving the screw
can be eased considerably if the
threads are given an application
of wax. This is preferable to
soap, which has a_ tendency to
rust the screw threads.
Some basic safety rules that
apply to the use of screwdrivers:
• Make sure the tip fits the
slot of the screw; not too loose
and not too tight.
• Do not use a screwdriver as
a cold chisel or punch.
• Do not use a screwdriver
near live wires
• Do not expose a screw-
driver to excessive heat as it
may reduce the hardness of the
!blade.

'in order to regain a good straight
, 'edge.
