[TR] Replacement bolts

[Bob Danielson]

Angelo,
I'm not a TR2 guy but on a TR6, bolts for the drive shaft flange, axle
flange, front calipers etc are bolts with precision shoulders. They're made
to a higher tolerance than a standard bolt. That's why they carry a premium
price.

Subject: [TR] Replacement bolts

Hello List:
  In attempting to replace some of the nut/bolts in my TR2 project, have
found it difficult to find the exact bolt, especially for bolts with
unthreaded shanks in various lengths. How important is it to get bolts with
the exact unthreaded shank length? Most of the replacements I have been able
to find are threaded the complete length. Does this present a problem when
replacing an unthreaded shank bolt?? Thinking mainly of the driveshaft
flange bolts and rear backing plate/axle attachment bolts.
I've always understood that most of the fasteners are "fine" thread - NF.
Have seen listings with threads per inch of 24, 20 and 18 on larger bolts
all as "fine" or NF. Am I missing something here or all they all considered
"fine" and vary by size of bolt.
Thanks for any help with this.
