[AT] Nuts n Bolts, bolts mostly...

[CEE VILL]

Just some BOLT thoughts!!!  (Notice I do not use the word NUT in this text)

The major diameter of the thread is usually a few thousandths smaller than 
the bolt shoulder, Matthew.  If alignment of the thicknesses being fastened 
is of consequence, the shoulder is necessary to do that job.  If side 
stresses are involved in use, the thread, being an interupted surface will 
flatted down quickly.  Bolts for certain specific applications are threaded 
the full length, as with carriage bolts.  I do not think they are intended 
for heavy load applications.

If a hardened temper bolt in not necessary, some guys do cut a threaded rod 
to needed length and tack weld a nut on for the head, or double nuts jammed 
together.  I guess it is usually depends on what is needed for the 
application.

With fasteners being as devirsified as they are today, I'll bet that even a 
huge bolt inventory gets stymied once in a while.
