Bolt Specs....?
(OP)
I have a drawing with a bolt description:
2x4 LG S.F. Tap Bolt - 8thd
Can anyone give me a heads-up as to what these terms mean?
Thanks a bunch.

RE: Bolt Specs....?
However the term "S.F.Tap Bolt" appears to be an abreviation of Self tapping bolt, and I haven't come across a self tapper this big before !
RE: Bolt Specs....?
I asked around and no one picked up on the "S.F." part, still asking.
RE: Bolt Specs....?
"thd" is the same as "tpi" (threads per inch)? I would never have guessed that.
RE: Bolt Specs....?
Another quirk is the length callout on fasteners, especially studs. If nothing is said the length will be end to end which takes a little usable thread off due to the chamfer. More and more people were calling out 1st to 1st , the first good thread. Now that material cost has gone through the roof the callouts are back end to end.

Thanks again.
