#3 Heavy Hex Jam Nuts

Heavy Hex Jam Nuts are thinner than regular heavy hex nuts, but have similar dimensions across the flats and corners. Like regular hex jam nuts, heavy hex jam nuts can be threaded onto a bolt and run tight against the standard heavy hex nut which will lock the nut in place and prevent it from backing off.
