I just bought a compound miter saw (Mastercraft 8.25", 55-6814-8), which
looks identical to the one in the following picture:
The manual did not spell out what size of wood screws or metal bolts should
be used to mount the saw to a wooden or metal work surface. Is this screw
size a particularly standardized one? Any suggestion as to what that
diameter might be would be greatly appreciated. Thanks
FWIW, your link did not work for me, nor do I have a Canadian Postal code.
Don't worry too much about it ... just get a bolt/screw that will fit the
hole, and is of the appropriate length to get the job done.
With a bolt, a washer or two - flat washer on one side, lock washer on the
nut side - is generally a good idea also.
When I mounted my miter saw to my bench, I used the largest diameter bolts
that would fit easily through the holes. If I were to guess, I'd say 3/8"
carriage bolts, long enough to give about 3/4" to an inch of thread to work
with when they came through.
Please do tell, oh, great supreme [facetious] one, <with a bow>, :-) In all
seriousness, your remark is right on yet polite. Yes, I do know how to check
using a tape measure. FWIW, seems like at least two manufacturers are using
3/8" diameter for those mount holes: Mastercraft and the one who made
Clint's miter saw.
Just a suggestion, but take out your tape measure, and measure the holes.
You'll also want to measure the thickness of the countertop, and how much
extra you need sticking through the saw pieces.
If it was me, I'd probably suggest trying to standardize (as much as
possible) on one size bolt to use for your equipment. 3/8" is a nice number
in my garage. Then hike on over to HD, buy boxes of 3/8" bolts in a variety
of lengths (say 2", 3", and 4", plus maybe a few in the 1/2" increments),
along with several boxes of nuts and washers. Oh, and grab some wing-nuts
to fit on there, as well. That way, you'll be able to use the same size
wrenches on most of your equipment, and you'll have a bunch of lengths to
work with. It's also considerably cheaper to by "by the box" as opposed to
bagging up 4 at a time. You might blow $30 up front, but the odds of having
to run out to the Borg at an in-opportune time is much reduce. I try not to
buy individual pieces of hardware anymore, unless I'm SURE it's a one-time
Of course you can buy them, silly...just call the equipment
manufacture's parts department. :)

No need for any more than one trip. Measure the holes. Measure the surface
you are going to bolt it to.
Of course I did. You are missing my point. It is a user's responsibility to
RTFM before using an engineered equipment, but it is also the duty of the
manufacturer to produce accurate and complete documentation in the manual,
which is, in this case, not only incomplete but also poorly written. Just
because I know how to use a tape measure does not release the manufacturer's
responsibility of FULLY documenting the product.
the manufacturer of the saw did not manufacture the bench. therefore
they have no control over what hardware will be necessary to make the
connection. I mean, get real, dude. it's a bottom end chinese miter
saw. it's meant to either languish unused in a hobbyist's shop or be
consumed as a disposable on jobsites where abuse and/or theft are
uncontrollable. you're lucky they even gave you mounting holes.
I have to disagree. The manufacturer of the saw made the mounting holes, and
every mounting hole has a fixed diameter. In terms of safety considerations,
it would have been a badly engineered product if they hadn't provided
mounting holes to fasten the saw on to a workbench. The manufacturer of the
saw DID provide the mounting holes, so why not the documentation of the
diameter of the hole?
I'm pretty sure that the mechanical engineering team who designed the
product has an exact number for the diameter of the mounting holes (or every
screw for that matter). The CAD/CAM draftsman or operator would need that
number. Somehow, someone along the way thinks that it is not important
enough to document it or someone thinks that it is in their best interest
not to document it.
If it is just an example of "familiarity (through standardization) breeds
contempt", I would accept it as an acceptable explanation to this newbie to
the world of carpentry. That is the reason why I asked in my original post
whether saw manufacturers have standardized on the diameters of these
mounting hole or not.
Sorry I asked this question in a carpentry forum. Perhaps a better forum to
ask is a mechanical engineering forum.
Because anyone w/ an eye could tell the size simply by looking at them,
and if not, it would take about 15 seconds (30 at most) to measure them
Actually, this is such a trivial issue it wasn't worth asking to begin
with...no one here could see your particular saw and you could have
measured them 10-times over in the time it took to post the original
message and you could have been to the store, bought the bolts and put
them in in the subsequent time wasted... :(
