Screwdriver bits PZ1, PZ2, PZ3, PH1, PH2, and PH3 are specific types of screwdriver tips used for tightening screws with a cross-shaped groove. TORX bits are another type of screwdriver tips, but they have a different shape than cross-shaped bits. Instead of a cross, TORX bits have a star-shaped design. These bits are labeled with the letter "T" followed by a number, such as T10, T15, T20, and so on. Each number indicates the size of the bit.
PZ (Pozidriv) and PH (Phillips) bits:
- PZ1 and PH1: Used for smaller screws with a cross-shaped groove.
- PZ2 and PH2: The most commonly used type, suitable for medium-sized screws.
- PZ3 and PH3: Used for larger screws or where higher tightening force is required.
