Again as Lynn mentioned there are lots of different sources for bolts. Something to note, SAE didn't list a UNC (corse) thread grade 8? bolt at all. Yet my local hardware store has all kinds of nice cromated (yellow) corse thread bolts listed as grade 8! Trust is everyting here people. I would trust ANY grade SPS bolt against ANY grade from china. Generally very good stuff. I highly recomend locating a copy of Carrol Smith's book Nuts Bolts, Hardware and Plumbing (24.95 @ amazon). This is a SUPER source of information for the layman. I am going to buy my third copy soon, they really tend to grow legs and walk off. The car racing community sells lots of jigs for drilling bolts for safety wire. Getting the aircraft hardware that comes that way is even better.
