* Robertson (SQ): Square-shaped

Screwdriver Tip Size

The second part of a screwdriver set number refers to the size of the screwdriver tip. This is usually denoted by a decimal number, such as ".150" for a 150mm tip. The tip size determines the width and depth of the screw that the screwdriver can fit and drive.
