bolt size for Nishiki cage

bike. I know that it has a brazed on mount, but am not sure what size
bolts are used. Any idea?

5 mm x 0.8 (a.k.a. "M5")
Any bike shop will have these, as will any metric-aware hardware store,
it's probably the most common metric size.

On bikes, yes.
On cars and motorcycles, M6 (6x1.0) and M8 (8x1.25) are the two most
common sizes.
Even Home Depot and Lowe's carry M5, M6 and M8 in a small range of
lengths and head types now. The US is slowly adapting to the metric
reality of the rest of the world. (But I don't think we'll see pipe
threads go metric in the US in *this* century.)

For contrast, the most uncommon is probably M7 (7x1.0). These are for
all intents and purposes unavailable anywhere. Unfortunately Vitus
chose this size for the saddle rail clamp on their 992's proprietary
seatpost. Equally unfortunately, they break. In the eleven years I've
owned my 992 I've broken two. The first time the factory sent me three
replacements, gratis. I am now down to one spare. :-(
Does anyone know where one might find M7x1.0x35 socket head cap
screws?

Poor Hoover put his heart and soul into that one success of his presidency.

have you researched re-threading to m8x1? probably an obvious
suggestion....

Dear Adam,
Keep in mind that Hoover was the only
president up until then who was an
engineer. He was quite successful,
translating "De Re Metallica" among
other things.
The other presidential engineer was
Jimmy Carter.
Washington the surveyor and Jefferson
the tinker deserve asterisks, since
engineering was hardly formal in their
time.
For all I know, the Senate and the
House may be littered with engineers,
but none spring to mind. The most
popular pre-legislative profession
before our rulers embrace a life of
crime may be lawyering, but perhaps
I repeat myself.

Wurth undoubtedly has them, but you may have fun figuring out how to
buy less than a box, and it's not obvious which of their divisions may
have it.
I suspect that I could get them through a number of industrial
fastener suppliers here, but perhaps there may be an alternative.
Someone already suggested checking to see if rethreading to 8x1.0
would be possible; the same advice applies to SAE5/16x24, in which
it's easy to get grade 8 socket head cap screws.

Oh the shame of it.

we physics folk have always liked to claim him on the basis of his graduate
work in nuclear physics and reactor technology ..
wow, they don't offer that anymore.
.. but it's kind of a stretch to say he was educated as a physicist since he
was more, as you say, of an engineer. the funny bit, tho, is that if you
went to school for physics you'd know that the navy nuke program just spams
you with solicitations and the navy nuke program is where jimmy carter spent
his time.

seems a little pricey, but what can you do? I found this by searching
Google for "m7 socket cap screw," and presumably there are others.
Surprisingly, McMaster-Carr does not appear to carry M7 screws, but I
bet there is a similar outfit that does. I also got a few hits
relating to Citroen 2CVs, so maybe you could find a 2CV and disassemble
it looking for the M7 bolt (somehow it's not surprising if there's
an M7 bolt in a 2CV).
I like the idea of rethreading to M8, but you might also have to
enlarge the bore and countersink for the bolt head. IMO, the
underlying question is, why do you break the bolts? Most seatposts
use M8, which isn't that much bigger/stronger, and American Classic
posts use M6. Is the rail clamp poorly designed? Are the bolts
a low grade steel? Then the grade is something to consider when
hunting for replacements.

I've actually considered this alternative. Meanwhile I still have the
one spare bolt so it's not yet a critical problem. I might try the
factory again, but I'm not sure they are still in business. :-(

Dear John,
One of my motorcycle world spies just reported that:
. . . the bicycle fellow looking for 7mm
stuff can order what he needs, one bolt at
a time, from any Honda MC shop, and possibly
even Honda industrial engine shops. I think
that Aaron's metric screws mentioned in your
email makes you purchase in lots of 10.
Here are 2 Honda part numbers for 7x38 (sorry,
not 35. what's 3mm between friends?) socket
head cap screws
90151-MB0-000 for 2.27 each
or
90151-MJ4-700 for 2.39 each
In that first part number, it's all zeroes.
