What are knobs?

Knobs are mechanical components which allow efficient tightening and loosening of screws.
Their best feature is that they are usable without tools.

Advantages of Using Knobs

Higher Work Efficiency Without Tools

The use of knobs increases work efficiency, since tools such as the wrenches and spanners used on screws are no longer required.
Efficient in places where screws are frequently handled, such as equipment changeover.
