Internal hex screws are problematic because the bearing surfaces through which the tool's force is transmitted to the screw are extremely narrow. This can damage the screw head. Hex-Plus tools have larger bearing surfaces that prevent this type of damage. And it's worth remembering: Hex-Plus tools fit any standard hex screw!

Extra-tough tips

Wera's extra-tough (Z) tips prevent premature breakage of the tip end. Z tips are typically the most suitable tips for universal applications.
