In that case I doubt I'd bitch about the $80 cost for 4 bolts.

thought I did.

with a less expensive source?

Since I presume you're dealing with an experimental aircraft, and a
MS20074 bolt is a coarse thread (the only coarse thread aircraft
structural bolt I know of), 125 ksi, drilled head hex bolt, why not
just use a grade 5 or grade 8 auto bolt? They are quite good quality
if you buy from the right source. Try some of the race car suppliers
maybe.

It might be quite good quality - or it might be junk.

How are you going to know???
If you go with a quailty manufacturer that will certify the grade, specify
rolled threads, and have them individually magnafluxed, you should be good
to go.
