Answered my own question, looked up nutsandbolts.com. Good prices! I have bought grade 8 hardware from the same aircraft supplier for 30+ years and always used wavy thread lock nuts...I guess I should look around once and a while...LOL! Thanks for the update.
Attn: Aircraft folks...is the gold color plating on grade 8 a required aviation standard? I just saw black oxide grade 8 bolts from a Case farm equipment dealer...never saw it that way.
