Screwdrivers are a
type of hand tool used
for the insertion and removal
of screws. They are available in
a multitude of variations to
correspond to the correct
screw drive. The drive or
head of a screw has a
shaped cavity and protrusion
that fits the screwdriver tip.
Primary hyperoxaluria type
2 (PH2), caused by mutations
in the GRHPR gene, is an inherited
disease in which the lack of a
particular liver enzyme causes
the body to accumulate excess
amounts of a substance called
oxalate.
The tool used to drive a
slotted screw head is
called a standard, common blade,
flat-blade, slot-head, straight,
flat, flat-tip, or "flat-head"
screwdriver. This last usage
can be confusing, because
the term flat-head also describes
a screw with a flat top, designed
to install in a countersunk hole.
