The Wera Kraftform Micro 2054 Hex Head / Allen Key Screwdriver has their ergonomic Kraftform handle and free spinning cap which makes adjustments comfortable, quick and easy.

They are made with Wera's Hex-Plus technology that's designed to greatly reduce the risk of stripping screws or nuts by operating with a larger contact surface and allows up to 20% more torque to be applied over a standard hex wrench, the Wera Black Point tip ensures size accuracy and provides corrosion protection. 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.
