What is the advantage of a ball end hex key?

The ball end on a hexagon key allows it to be inserted smoothly into a socket head. This ability to slide in allows for easier blind insertion, allowing you to more effectively feel the keys way into the socket more easily. As such, for difficult to access sockets, ball end hex keys are preferable.

These blackened and heat-treated hex keys have a degree of corrosion resistance, however, correct storing of your tools will increase their useful life. It is recommended that the tools are stored in a clean and dry environment.
