Thread/shank lengths very random

Some bolts (of equal length) were threaded full length, others had long shanks, short threads. A few the square-head bolts had maybe 1" of threads, barely enough to be usable. Very random, needs to be more industry standard, or at least say in the description what the shank/thread length is.
