bad chinese a325 bolts
the following is an email that was forwarded to me recently. wondering if others have had similar experience.
from: s.e. llc. [mailto:
we had a similar problem 15 or 20 years ago with counterfit bolts. we began specifying only domestically produced bolts and haven't had a problem since. demand to see the paperwork from the supplier or have them independently certified as meeting a325 specs.
