[TR] Triumphs Digest, Vol 4, Issue 16

 Indeed.  Best commercial practices call out full engagement with some exposed
thread  I've seen Mil Specs that call out two full exposed threads.  This
doesn't add strength but it does aid in visual inspection for compliance.
Also, I've been told that any engaged thread length in excess of the fastener
diameter doesn't add any strenght, either.  But having a bolt that doesn't
protrude through the nut leaves one wondering just how much engagement there
really is.  As Jerry said, I would advise against it.

A former member of my local club ran steel wheels on short studs. He used the
deeper lug nuts for steel wheels. The threads only engaged about half the nut
depth. This always gave me the willies because I was taught that one thread
should protrude from the nut.

But, I can't recall this causing any problems.

Even so, I'm not advocating it.
