EIGHT Super Ball Point Set of 7 with Tightening Type Pipe, Semi-Long TMS-7DP

Comes with a pipe for tightening. The six faces of the tapered head (ball point) fit tightly against the bolt, resulting in less wear. The tapered head is finished with precision using a unique manufacturing process, resulting in a uniform finish. Whether used straight or at an angle, the contact surface with the bolt hole is large and it will not slip. Special alloy steel is used for excellent wear resistance and can withstand high torque. The holder is a compact two-tier type that can be easily inserted and removed. Set contents (mm): 1.5, 2, 2.5, 3, 4, 5, 6, pipe Material: SNCM+V Special Finish: Hard chrome plating
