The problem
One wrench that fits every bolt and nut
Tired of hunting for the right wrench for every bolt size? The universal wrench with automatic adjustment grips hexagonal nuts, round pipes and worn bolts – without switching tools. Pick your size, place the head and turn.
How it works
Six steel segments that close in and hold
The head holds six moving steel segments that adapt automatically to the shape of the fastener as you turn the wrench. Hexagonal, round, square or damaged – the segments form around the edge and hold without slipping. No separate sockets to keep track of.
Where to use it
At home, on the bike and under the hood
The 15 cm version is compact for quick fixes in the home workshop and for bike repairs. The 20 cm version delivers more torque for heavier jobs: car maintenance, pipe installations and ventilation work. The soft foam rubber grip dampens vibration and protects your hand during longer sessions.
Choose the right size
15 cm or 20 cm?
- 15 cm – Lighter and more compact. Suits home repairs, bike servicing and tight spaces.
- 20 cm – The longer arm delivers more torque. Best for car maintenance, pipework and heavier bolts.

FAQ
Questions and answers
Which bolt sizes does the wrench fit?
The wrench fits hexagonal nuts and bolts, round pipes and irregular or worn fasteners. The six steel segments adapt to the shape automatically.
How does the self-adjusting head work?
The head has six moving steel segments that close around the fastener automatically as you turn. No manual adjustment is needed – just place the wrench and turn.
Does it work on worn or damaged bolts?
Yes. The moving segments grip whatever shape is left, even when the bolt edges are rounded off or damaged. That makes the tool especially useful where an ordinary wrench can no longer get a hold.

The 15 cm version is compact and easy to handle for home repairs and bike servicing. The 20 cm version gives you a longer arm and more torque, best for car maintenance and heavier work.
