I am looking for something like a coach bolt fixing but instead of the usual
square or hexagonal nut I want a threaded sleeve with a dome headed end like
the coach bolt itself.. Do such things exist ? - if so what are they called
and where can I get them ??

Thanks

How big?

Kitchen cabinet connectors might work for small applications (metal, 5mm
diameter 30-40mm long; various coloured plastic ~8mm diameter maybe a bit
longer than the metal ones)

Or you could use ordinary coach bolts with dome nuts (like standard nuts but
the end is closed with.... a dome!)

Screw fix sell both sorts if you want to look at a picture. (they call the
cabinet connectors "Inter Screws")

Thanks Adrian - the metal version is the sort of thing I'm looking for but
I need something around 50-60mm + it has to be quite heavy duty and I need
something that doesn't protrude as far as the dome nut.

A threaded sleeve like that is called a tubular nut - this type of
fastener must be tightened from the bolt end, which wouldn't be possible
with a coach bolt.

When I said coach bolt I was really referring to a flattish dome-headed
type bolt (which could be slotted) so I guess it is more like a roofing
bolt. Where can tubular nuts be found ??- Google doesn't find much on
this.

I suspect that they're usually specials for each application. Maybe you
could use a connector nut (just a long nut to take a screw in each end)
with Allen socket mushroom head screws? Of course if we knew your
application ...

Off the top of my head you need a tubular nut. Suzuki gt250 motorcycles of
1975 ish vintage used a long tubular 8 mm thread cylinder head nut, the head
size was 14 mm with a flange washer built in, you could reduce the height of
the nut head as much as you need, the tubular part was about 60mm long, od
about 12mm. My shop used to sell them, but it has closed long ago, but any
suzuki dealer would be able to get them. How many do you need, I may have a
small number lurking somewhere.

http://rswww.com "Hexagon Connecting Nuts".

The range starts at 276-522 (M6x18mm) and goes up to
276-572 (M20x60mm).

A range of M6 and M8 roofing bolts (12mm to 80mm long)
starts at RS part number 277-604.

Thanks for the suggestions - It's just to bolt length of approx 8" x 2" as a
bench seat to metal brackets coming horizontally from a wall and I don't
want any bolt ends protruding or anything sharp that for example could
damage a child crawling underneath ! Your suggestion of the Allen socket
bolts with a connector nut will do the job I think.
