Compression Latches

I have those same kind of latches and several have broken over the years. They are only made from that cast pot metal and are brittle. I did not want to replace them with the same type and have them fail also. I ended up removing the broken section inserted a 5/16 allen key into the hex hole. I had to grind the key down to the right size and it works fine. I think I contributed to the latch breaking because several doors leaked and I tightened them the adjusting bolt. The new ones are steel and will never break.
