For the record, a socket head cap SCREW such as the "subframe Bolts"
that seem to break is measured by the length under the head, not the
total length. I encountered the same kind of misunderstanding when I
ordered a box of shiny new 14mm nuts for the late model c/shaft,
(Which requires a 20mm) which I will never be able to sell, based on
someone's word. Also, for the record, SS is between SAE grade 2 and
5 in tensile strength. The capscrews I ordered are metric 12.9,
which is a chromolly steel, higher strength than 10.9 (SAE grade 8).
Soon as I get time, I'll try to address these points in my website,
which, by the way, is looking PRETTY FOXY, Mark!

m8x30 or m8x25?
Jake,
The 8X30 that I reported earlier today was from Kawasaki. I know that bolts
are measured from under the bolt head and not over all length. I also know
that bolts are not called by the head diameter but the shank diameter. I
get this everyday, when someone asks for a 10mm bolt I have to ask do you
really mean a 6mm bolt. There is a "slight" difference there.
One thing I have learned over the years is that you don't take a customers
word for a size on anything unless they put their money down first. Better
to do your homework first and then order the correct sizes. Sorry to hear
about your extra nuts. (we already knew you were a little goofy)

I think that a shear-sensitive frame joint, held by a small, threaded
fastener, being acted upon by large leverage forces, is risky by its very
nature. Fred and I would design it differently. If a couple of bolts at
$2.00/pr gives listers a sense of security, an improvement over stock,
where's the harm? Maybe there's a point where NO fastener would survive;
representing a warning that the rider is carrying TOO MUCH LOAD. I stand by
my recommendation, Walburn to the contrary. The fasteners I ordered and
will supply, may not allow the doing of serious air with a passenger aboard;
sometimes the dragon wins. Evidence: the Ride To The Moon experience.
That's why I avoid mounting setups for the 1600 PelCases. Thank you RM, for
helping me make the case for MY centerstand bolts!

That's funny. You should have given him Fred's phone number and said, "Here call this guy. He can overnight you one." Pat / Austin> would be in "in a week or two
