Bansbach Easylift 27995 A4 Ball Stud Kb16M10*20Bl, Steel, Right Hand Thread

The ball head part of the screw is indeed 16mm in diameter. Also, the thread length is indeed 20mm as well as height from the base to halfway up the ball being correct at 16mm. The incorrect dimension on this part was the thread diameter which was incorrectly labeled as m8 but when measured is closed to a m10 at 9.93mm in diameter. With the thread sizing being incorrectly marked this caused me to order the wrong matching nuts and lock washers for the part.
