[Features] ● The material is super-strong alloy steel. ● Spring steel and steel balls are embedded in the ball point of the head (3.0 mm to 10.0 mm). Firmly holds the bolt from the inside, making it convenient for tightening screws in deep places. In addition, by adopting a new structure for the ball point part, it is possible to work at an inclination angle of 25° on one side. The steel ball has a hardness of 60 degrees HRC or higher and will not wear out.
[Applications] ● Fastening cap bolts and set screws.
