The Wera Kraftform Micro 2052 Ball End Hex Head / Allen Key Screwdriver has their ergonomic Kraftform handle and free spinning cap which makes adjustments comfortable, quick and easy.

The screwdriver features a hexagonal ball end tip which means the screw can be adjusted even if the tool is not directly on centre, great for hard to reach screws. Wera's Black Point tip and a refined hardening process ensures size accuracy and provides corrosion protection for a long service life. The bottom part of the handle spins freely from the rest of the handle so you can anchor this in the palm of your hand while using your thumb and fingertips to quickly rotate the handle, the thicker part of the handle toward the centre provides a comfortable area to apply extra turning force if required and the hexagon shaped handle allows precision turning and stops the tool rolling away between uses. Each screwdriver is size labelled and colour coded with Wera's "Take it easy" tool finder system on the handle so you can quickly find the size and tip profile you need.
