Several people at my club have had the same problem over the last couple of years on their newer Beiter wrenches when the older ones don't show this problem, It's probably like a lot of things in life the older version was better made. I have no problem with the button, this will become a family inheritance, it's so well made, but the wrenches are certainly not so good now. I guess I'll have to go the home made route. Thanks to everyone for their answers.I still have both of mine from my 1st Beiter button and it's 16 years old, either the quality/strength has gone down hill (unlikely) or your tightening yours down with way too much force, on a more useful note some SF buttons and probably other types aswell come with a metal tool that can be used to tighten down a Beiter button.
