Sure it follows... kinda... but a stud does not have a head

I guess if you take the side of the discussion that the length listed should reflect only the length of the fastener that is free for use fastening things and not its total length (as in bolt/screw descriptions)...
BUT, IMHO a stud is somewhat special... unless the threaded portion that is not part of the length listed is standardized you would end up with the same listing description for studs with entirely different overall lengths... It may very well be that there is some DIN stud standard out there that specs this out so we don't have this issue.
John:
The Dimension column... is that what you measured?? or from your book?

PS: Nowhere else but this board could we have such an arcane discussion and not be the laughing stock of the pub

speaking of pub... I need food
