TYPES AND USES - Continued
CROSS-TIP SCREWDRIVERS
The tip of a cross-tip screwdriver is shaped like a cross
so that it fits into cross-tip screws. Cross-tip screws have
two slots which cross at the center. These screwdrivers
are made with four different sized tips. Cross-tip screw-
drivers also have different length blades ranging from 1
inch to 8 inches.
CROSS-POINT SCREWDRIVERS
Cross-point screwdrivers are similar to the cross-tip.
The cross-point slots meet at an exact right angle at their
intersection. These screwdrivers are issued in 3 to
8-inch sizes.

Clutch head screwdrivers are used to drive clutchbit
screws. These screws have recessed heads and are
commonly called butterfly or figure-eight screws. There
are two styles of clutch heads, old style and new style.
OFFSET SCREWDRIVERS
Offset screwdrivers are used to drive or remove screws
that cannot be lined up straight with common screwdriv-
ers, or are located in tight corners. Some offset screw-
drivers are made with two blades, one of a different size
at each end. Others are ratchet-type offset, which are
reversible for working in tight spots and allow the screw
to be driven without having to remove the tip from the
screw head. A double-tip offset screwdriver has four
blades.
