Re: Fastener materials and grades
Grade 8 bolts are not used in the ultralight aircraft industry because they can be have purported to be "brittle" if used wrongly.
What can you comment on AN hardware? I have read/been told by "experts" it's the same as grade 5 in hardness. I also have been told it's "army/navy" hardware, and not aircraft specific.
AN hardware sure makes the use of fasteners easy!
Thanks in advance!
