5/16" Dia. Carriage Bolt - Smooth

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.

Great product. Didn’t realize how much I would like a nicely painted carriage bolt lol.

The product is of high quality. Very pleased with how it makes my historic project look. It was delivered on time as promised.
