Wise PIS358 Piercing Ball Wrench A Set (3/5/8)/Great for Small Places

[Specifications/Features] Made of high quality chrome vanadium steel. It is tough and easy to use, and it has two sizes to use. Traditional hex wrenches require a minimum of 60° repetitive angles, but the piercing ball wrench can be tightened at a 30° repetitive angle. The secret is that it has been processed (patent) with a 15° shift to the axis. This makes tightening work easier in narrow areas. PIS-304, PIS-506, PIS-810 are included in the set. [Precautions] Do not use for anything other than the intended purpose. After the screw has stopped rotation, it is necessary to apply strong torque to the handle over 45 degree twist.
