bolt size for Nishiki cage

Ryan said:

I just bought a water bottle cage for a Nishiki (c. 1993) mountain 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?

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.

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.
