My review about Hex Key / Allen Wrench

In electrical or maintenance tasks,i like to use the T-handle Hex key.Why?? In my experience,it very comfortable when i drive the hex head.I got more torque and can tighten the screw more efficient.I also can perform the task in a narrow space.

It very easy and can get through any area or space condition.If perform in live electrical tasks,for safety please using the VDE or Insulated Hex Key types.For more detail please read about Allen wrenches review
