Wera Self-Adjusting Open-End Wrench

With this Wera open-end wrench, there’s no need to search for the right size: the continuously adjustable parallel jaws automatically adapt to the nut or screw head at hand, without any manual adjustment.
A single wrench thus covers an entire range of sizes, which significantly lightens the tool kit and eliminates unnecessary trips back and forth.

The smooth jaws do not grip the edges but distribute pressure across the flat surfaces of the fasteners, significantly reducing the risk of rounding off a nut or damaging a screw head.

The built-in ratchet function rounds out the set: it allows for continuous tightening or loosening without having to disengage the tool after each turn, which significantly speeds up repetitive tasks.

An integrated hanging loop allows the wrench to be hung up for storage.
