What is the difference between a steel bolt with a hardness marked 8.8
and a stainless bolt marked A2.70 (or TH5)? The fan blade bolts came
loose on my 67.5 and 3 broke, while the fourth one was 3/4 gone. The
original bolts had a rating of 8.8, while the stainless bolts (the only
ones I could find that would fit) are marked A2.70.
Another question is if Stainless is a better material for use on fans.
I believe that it is not as brittle as steel, but I'm not sure.
Thanks in advance!
Peace,
Pat
