I think this might be metric bolts because they dont appear to be SAE.
I am puzzled what they are referring to.
I bought a used Makita table saw at a garage sale. It needed a few
repairs which I took care of. I got a downloaded PDF file from their
Makita website to help me determine what went where. I got it all
together and it works except the rip fence is missing a bolt that
makes it clamp sloppily. My parts can does not have anything that
will fit, so I'm off to the hardware store later today. The parts
list in that PDF file show this bolt as "Hex Bolt M6X16". WTF is
that? I am assuming the "M" means metric. Is that correct? I am
assuming 6X16 means 16 threads per inch. (that looks about right),
but what is the "6"? 6 centimeters long, or is it 6cm thick? There's
a number missing either way......
Now looking at it in SAE terms, it's about 1/4" thick, fine threaded,
and 1/2 to 5/8 inches long, and the head is roughly 3/8" hex.
Damn I hate metric shit...... I wish I had been born 100 years sooner
so I'd never have to get frustrated by this metric crap. I was born
in America, that means I should be speaking English, and using inches
and feet, not speaking a foreign language or using goddamn metrics
from countries that dont know how to measure things. Yep. metrics are
one of my top pet peeves that really piss me off........
At least they dont have the rip fence ruler in metric, or I would have
not bought the saw. At my age, I am too old to change to metrics
You would still be better off if you did it tomorrow.
What's the impediment except for guys like the OP.
All of your multinationals manufacture things for the rest of the
world in metric sizes. Your manufacturing industries would be much
more competitive if they turned over to the right side. The only thing
that keeps imperial measurements going is a reasonably large domestic
market, and that will evaporate in the next few years in the face of
foriegn competition (China).
OOPS..... I guess it would be a sin and sentence to hell to use the
word "inch" on a metric bolt. I suppose it's threads per kilometer or
some such nonsense. This alone is proof that metrics are meant to
drive people insane. They are made for the criminally insane, because
after using them, one has an urge to kill whoever made the bolt
Thanks for the info, and yeah, it's MM not cm....
So, are all metric bolts the same thread pitch since they dont list
It's so much easier to say I need a 1/4" bolt 1" long with 24 threads
I think all metric bolts should be sent back to their own country of
origin, and the US governement should ban them in the US. If for no
other reason, they are anti-patriotic. America was built with inches,
feet, yards and miles..........
I thought so at first too, but when I checked tables, seemed t'other
way around. But seems like I misread the table. You're right. Oops ;-)

Metric makes a lot more sense (it was designed that way). We just know
what we're used to. For example, what horsepower light bulbs do you
use? I don't know either, I use the dreaded metric unit--watts.
Familiarity with the metric system would have saved a couple of Mars
missions and about a gazillion dollars.
I really dont understand how it can make more sense. Do you really
think anyone can remember all these numbers? (examples below)
a 2X4 board = 5.08 x 10.16 (cm)
a 1x6 board = 2.54 x 15.24 (cm)
an 8 foot long stud = 2.4384 (meters)
4x8 foot sheet of plywood = 1.2192 x 2.4384 (meters)
30 miles per hour = 48280.32 meters per hour
1 yard of carpeting = 0.9144 meters of carpeting
How can you call this simple?
2x4 is easy to remember, not 5.08 x 10.16.....
And right there demonstrates why we are still stuck with this abortion
of a ?system?.
People who think that if you work in metric, you have to convert it to
English. One of the dumbest arguements agains changing that was ever
Please tell me why you would want to know what the English measure was
for a metric piece of lumber.
To find out how it spans studs 16" OC, perhaps?
The problem is primarily in having to mix the two and irregardless of
the theoretical niceties of metric vis a vis English, there is a
history dating back several hundred years that can't be whisked
away--if, for nothing else, for those raised using English, despite
"book-larnin' " about MKS, it just "ain't natural". As a trained
engineer working w/ metric for 30 years, there still isn't the inate
"feel" for ordinary day-to-day things in metric measures that there is
for English. I just don't think that I'm really putting in 19 l
instead of 5 gal so it's "only" 76.5 c/l instead of $2.90 /gal -- no,
all I'm thinking is the producers are making a killing at $75/bbl.
Similarly, it's going to be d-- near 100 out this afternoon...I don't
feel a bit cooler at whatever it is in C and I have to stop and
calculate it out rather than "just knowing".
And, even as we continue to teach mks in school, the common usage
remains (and will remain for the foreseeable future).
Also, I don't really agree w/ the argument advanced earlier that there
are really that many fewer sizes in metric--in actuality, it seems to
me there tend to be more, at least in the smaller sizes where it seems
you find stuff every mm.
I do agree that the 70s/80s transition period with mismatched fasteners
on a single product was an abomination--I had one of them as well.
I'm not sure how much it really affects US industry's overall
efficiency--as someone else noted, most export sales are and have been
metric for quite some time now and a great portion of that production
is not in the US anyway. I'm sure there is some affect, but doubt it
would make a huge difference in competitive balance if it were to
disappear overnight (which of course, it can't owing to all the above
Good valid points about what your are used to. The changeover, if it
ever occurs, will not be painless of course but the pain won't last
long. In a few years everyone except a few would be wondering why they
fought it. England made the change and never looked back.
There would remain the problem of matching up metric with stuff built
under the English system but it can be done (England for one).
That's what I recall the mantra being about the time my kids started
school--as is typical in the US, however, being no widespread public
"mandate", there was no way to get a universal acceptance and the
movement floundered. Despite the (more-or-less) common language,
there's a big difference between public/government dynamics in the US
vis a vis England. I don't foresee a switch in common usage for a long
time (TM). Even the campaigns for metric road signs (about as painless
as it gets) are all gone afaict.
Australia went cold turkey years ago. Worked like a charm. New
generations never even heard of the old system.
U.S. made a timid attempt years ago to put BOTH on road signs, e.g. as
a "transition. Of course people only looked at the familar system,
so that went nowhere and was abandoned,
