[Features]
Nickel-chrome plated for rust resistance and long life.
The edges are lightly chamfered, making it easy to insert the wrench into the screw hole.
It has a very high hardness of HRC59 and is constructed to be very strong, so it has excellent abrasion resistance, durability, and can withstand high torque.
The precisely manufactured ball point allows you to turn screws at an angle (up to a 30° angle is OK). *The ball point cannot be used for final tightening.
