These prefixes are typically followed by a number that indicates bit size. For example: PH2 – (Phillips #2) A large Phillips bit. PH0 – (Phillips #0) A medium Phillips bit. PH000 – (Phillips #000) A small Phillips bit. The PH2 wood screws are ver y similar to the PZ2 screws. This is the same size category. The differences appear in the choice of a screwdriver. A PZ (Pozidriv) screwdriver will also be pre-fitted with PH (Phillips) screws, but if you use it, the screw will be easily deformed. 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.
