Well there is a little more to it. I'm assisting other builders and the
bolt count goes up @ 4/ ship and it adds up quickly. I'm sure that there is
a source somewhere at more like $10/bolt I bought "Supertanium" bolts for
less than $20 each and these are a high strength Titatanium alloy in the
200ksi region.
The MS are of the grade 5 variety, coarse thread and the only thing special
is the drilled head. $20 each is excessive.

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

Yes, I want to be 500' in the air not even wondering if I got the bolts
that I thought I did.

out there
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.
