What does it mean when a bolt has a tapered head?

Answer 1

it means that the bolt is usually used to help line something up like a head or an intake,the taper helps to line them up,normal bolts don't have a taper on them,only bolts used to align things or parts need to be in perfect alignment will have tapered heads on them,good luck.

Answer 2

means the head of the bolt has a slant on it so it can be recessed

Answer 3

My husband who has been in construction for 25 years says it could mean that it is a lock nut bolt and most of the time the size is metric.
