Pozidriv was developed in 1962 by GKN (Guest, Keen and Nettlefolds) specifically to eliminate the cam-out problem that plagues Phillips screws. It looks similar to Phillips but is a completely different system - and the two are not interchangeable.
How to Identify Pozidriv
Look at the screw head. A Pozidriv screw has a cross pattern plus four tick marks (small lines) at 45° between the cross arms. Phillips has a plain cross with no tick marks. If you see tick marks, use a Pozidriv driver. Using a Phillips driver on a Pozidriv screw damages the screw recess and wears the driver tip.
Pozidriv Sizes
| Size | Tip Width (approx.) | Screw Gauge Range | Common Applications |
|---|---|---|---|
| PZ0 | 2.5 mm | #2–#4 | Small electronics, hinges, light fixtures |
| PZ1 | 4.5 mm | #4–#7 | Cabinet hardware, light switches, Euro hinges |
| PZ2 | 6.0 mm | #8–#10 | General construction, drywall, decking - most common |
| PZ3 | 8.0 mm | #12–#14 | Heavy construction, large hinges, structural |
| PZ4 | 10.0 mm | #16+ | Industrial and heavy-duty applications |
Where Pozidriv Is Standard
- European construction and cabinetry - Pozidriv is the dominant drive type in the UK and mainland Europe
- IKEA furniture - most IKEA screws that look like Phillips are actually Pozidriv
- European-manufactured appliances and electronics
- Drywall screws in European markets
- Chipboard and wood screws from European manufacturers (Spax, Heco, Wurth)
If you assemble IKEA furniture regularly, get a PZ2 screwdriver. Most IKEA cross-head screws are Pozidriv, not Phillips. Using the correct driver makes a noticeable difference in grip and speed.
