Bolt Shank/Unthreaded Section
Do 1/2" UNF and UNC bolts have a standard threaded section length?
For example how could i work out what length bolt to buy for a required unthreaded shank of say 2" or 3"
Cheers

Yes, there is a standard ratio of length of bolt to length of thread, but for the life ofe me I cannot remember it right now.
However, see the u2u I am just about to send you !
For everyone else, I will post details tomorrow, ( but someone with a better memory may be along any second).
Regards
Jon

Have a look at LAS Aero's website for a good explanation of the various standards (and some very good quality bolts) www.lasaero.com for UNF/UNC
the bolts are described by grip length. For American spec bolts it is more complicated.....

Acording to the ansi standard 1.25 is the length of threaded section for all 1/2" bolts under 6" long and 1.5" is the threaded
length for 1/2" bolts over 6"
that seems to the case for "standard imperial bolts" for the american designed stuff leaving here. there are of course plenty of
"specials"
