The DONGCHENG HD092900 9 PCS Ball Point Hex Key Set is made for mechanics, technicians, machine maintenance teams, cyclists, and DIY users who often can't line the key up straight with the bolt. The rounded ball end lets the key enter and turn a hex socket screw at an angle of up to about 25 degrees, so you can reach bolts behind brackets, inside frames, and under panels. The set covers the most common metric hex (Allen) sizes and comes in a compact holder for carrying and storage.

Safety Note:
Use the correct size key for the screw to avoid rounding the socket. Use the ball end for fast turning at an angle and the straight end for final tightening, since the ball end carries less torque. Do not extend the key with a pipe, and do not use it as a pry bar or hammer. Replace worn or bent keys.
