What do you call a bolt with thread only part way?

I need to buy some bolts to replace some rusted and
corroded. The bolts I have hexagonal heads and a smooth
shank from the head to about halfway down, where the thread
starts.

Looking online I find most bolts have a thread from the
head all the way down, this isn't what I want.

Also, I only need to buy three, can anyone recommend
somewhere I can buy bolts in small numbers, these are 9mm
by 50mm A2 stainless, and not cheap (I've found 9mm x 50mm
threaded all the way at about £85/100, I definitely don't
want to by 100 when I only need three!).

A bolt.
If fully threaded they are a set screw.

You want a bolt with a plain shank, rather than one that is fully threaded.

I would buy them from my local industrial fastener supplier, who is
perfectly happy to delve into one of the many apparently identical brown
boxes on his shelves and come up with one or two of exactly what I want.
However, like traditional ironmongers, I suspect he is one of a dying breed.

If you're near London then Clerkenwell Screws will
have what you need. They probably do mail order as
well, although I'm not sure how quick they are in answering
the phone,

For OTC they're on Clerkenwell Road and in the Wembley trading Estate
as a quick Google will confirm.

Their website is down at the moment - which only ever served as a
catalogue in any case - but they do small quantities of screws in
most sizes (in 1mm increments) in most materials, i.e all types of steel,
brass and even nylon. They're not that expensive either

I haven't used them for around 6 months so I hope the fact that their
website is down isn't a bad portent.

A bolt is normally only part threaded.
A machine/set screw is fully threaded.
Coach bolts are normally only partly thread and have a round cap with a bit
of square shank to stop it rotating.

As others have pointed out, you are after bolts.

Screwfix do packs of 10 but perhaps not in the exact size.

For stainless bolts, try a Marina / Yacht Chandlers, if you are near the
coast- they tend to stock stainless bolts, screws, etc. and will sell them
in small quantities.

I'd agree with that, a coach bolt has a square head and thread
suitable timber.

That's a coach screw, tapered thread square head.

Coach or carriage bolts have a parallel thread, a domed head and
and a sqare section under the head which prevents the bolt
from rotating in the hole as the nut is tightened. Which
would otherwise be a problem given the domed head.

I wouldn't agree. A coach bolt is as Denise described (they are also
called carriage bolts) Coarse threaded screws that thread into
timber are called coach screws.

In normal engineering usage bolts are partly threaded, set screws
fully threaded.

You sure they are metric? 9mm is not a 'standard' size although they
are used on a few bike and car engines. Also you need to know the
pitch, either 1.25, 1.0 or 0.75mm. If they are not fully threaded
then you need to know the grip length - the length of the unthreaded
section.

You may find them difficult to find even from extremely well stocked
fastener suppliers, finding them in small quantities in stainless
could be next to impossible.

What is the specific application?

Depends on how big they are. They arent a set screw if they are big enough.

While set screws normally are fully threaded, not all full threaded bolts
are set screws.

It depends on what they do.

Not necessarily on that last. There are plenty of coach bolts
that are normal bolts with a domed head with a square just
under the dome to stop it rotating in wood and with a normal
bolt on the rest of it. In other words the only difference between
a coach bolt and a normal bolt is the head.

Coach SCREWS have a thread suitable for timber.

Coach screw is like a big wood screw but with hex. or square head.

Coach bolts used to have a rounded end with a square section that locked
into a square hole. the word coach is used for these due to them looking
better as just rounded domes on the outside of um, coaches.. I guess it
dates back to the old horse drawn days.

No these are coach bolts. I had a box of them described that way on the box
straight from the factory some years ago. There could be local names of
course but the main description was as I said in an earlier message.
I have a feeling the old British Standards manual has some words on all of
this congfusion!

Fraid not, most obviously with the smaller bolts that

Surely that's a coach SCREW? I think a coach bolt is as described -
round head with a square bit underneath.

Thanks for the reply, you've made me double check my
measurements. It's not easy when they've suffered crevice
corrosion (the leak was fixed last year, but I didn't
replace the bolts at the time).

The digital callipers say they're 0.3715"... or about
9.43mm. That's not M9, nor is it 3/8" which should be 0.375
decimal inches (decimal inches?! the mind boggles). I'm
guessing that 3/8 is what they are and either the callipers
are out or these were cheap bolts.

Thanks to all who replied, mostly a very helpful
discussion. I'll be giving the order to Westfield Fasteners
<URL:http://www.westfieldfasteners.co.uk> who appear to be
handy with qty, price and availability.

Justin.

I am near the coast, I can see the sea from here. Trouble
is, there aren't any decent chandlers in these parts -
there are no marinas, or estuaries for boaty types.

And, funnily enough, these are for my boat. The chandlery
where my boat is kept, is, I'm sorry to say, a poor excuse.
Not one of those lovely Aladin's caves one reads of (where
are they, I've never found one?).

Thanks for the suggestion.

I think those with thread all the way down are called 'set screws',
though I have no idea why.

Set screws are totally different.

Actually that sounds pretty close to me - I think the tolerance on the major diameter is about .007" for medium fit (which is the tightest tolerance recommended for bolts under 3/4"). That means the diameter could be between 0.375 and 0.367 inches.

I've heard of bolts which are partially threaded described as having
so much "wood", that is, say 2" of unthreaded shank would be described
as '2" wood', the idea being that often such a shank would pass
through a piece of wood being attached to, typically some sort of
metal fixture.

In fact even bolts that arent used with any wood at all
arent normally threaded all the way up to the head.

Who cares if they get this wrong in Oz - as so much else?

This is a UK group, and a bolt is a bolt here. Not a machine screw.

And most arent threaded all the way up to the head
with the bigger bolts even on that soggy little island.

That's useful to know. Thank you.

Westfield Fastners were quick to deliver and I'm over to
the boat tomorrow so shall install them then - if they fit!
