The Difference Between Phillips and Pozi Screw Heads

When working with screws, choosing the right type of screw head makes a difference. Two common types are Phillips and Pozi. While they look similar, they perform differently.

A Phillips screw has a cross-shaped slot. It was designed to allow the screwdriver to slip out if too much torque is applied. This prevents over-tightening but can cause cam-out when high torque is needed. Phillips screws are common in furniture assembly and electronics. You can find a range of Phillips screws and fixings here.

A Pozi screw, short for Pozidriv, looks like a Phillips screw but has additional small lines between the main cross slots. These extra lines reduce cam-out and allow more torque to be applied. Pozi screws are stronger and less likely to strip. They are often used in construction, woodworking and heavy-duty applications. Browse our selection of Pozi screws and fixings here.

The main difference comes down to torque and grip. Phillips screws are easier to slip under high force, which can be useful for delicate tasks. Pozi screws provide a firmer grip, making them suitable for projects that require durability. Using the wrong screwdriver can damage the screw head or tool.

Knowing the difference helps you choose the right screw for the job. Phillips is ideal for light tasks, while Pozi handles stronger applications. Both types are widely available at 55 Fixings, where you can select the size and finish you need.
