What these screws are called?

My wife received a dressing table stool today and asked me to put it
together for her. The seat frame attaches to the legs via a corner bracket
and a big chunky coarse wood cutting threaded allen screw. When I was
tightening the screw I could tell it wasn't 'biting'. The problem is the
predrilled holes in the legs are 6.5mm diameter and the diameter of the
thread on the screw is 7.0mm, giving 0.25mm per side for the screw to bite
into. The screw measures 5.0mm at the bottom of the threads, all measured
with a vernier, so they are true sizes.

I have spoken to the supplier (not manufacturer) and all they can do is send
a replacement which I think will be the same. I need some bigger diameter
screws but do not know what they are called. I have looked at Screwfix,
Woodfit, Toolstation and Unifix with no luck but I think it would be easier
if I had a name or type to go on. I did think of plugging the holes with
dowels and redrilling but if it doesn't work I have stuffed a £70 dressing
table stool.

If it helps to understand my ramblings this is the stool, (but doesn't show
the screws and bracket).

get some thin play from a model shop - 1/64 or 1/32" and roll it up and
glue it into the holes.

Or use glued in matchsticks.

Another trick is to grease the screws and stuff a little car body filler
in the holes, then nail the screws mostly in, and when the filler goes
off, tighten up.

Or completely plug the holes with filler, and redrill at 6mm or 1./4"

No they are not coach screws I have some of those and they are not the same
at all.

I did think of that but my 6mm plugs will not accept the end of the screw as
it is 5mm in diameter. As I said above I did think of dowels and redrilling
also but I don't want to cattle the stool and be left with a bill for
another one at £70.00

I'd ask the supplier to replace the legs. If you "fix it" (and there are a
number of options) and it later breaks, you'll have no come back.

A different matter if you've drilled the holes but that isn't the case.

I think its assembly screws then, the type you get in Flatpacks/Self
assembly furniture.Just had a look at a unit in the backroom and its got
these star headed screws in it however looking at the thread it just
basically a wood screw thread.
Should be able to get them in most sheds

That's the problem they cannot replace the legs only the whole unit and I
think it will be a never ending circle of replacements and returns. I even
asked them to put me and the manufacturer in contact but "We can't do that
Sir".

What I used to use for these situations was a plug of wire wool. What
I use now is a chunk torn off from one of the much more substantial
stainless steel scourers. Poke this loosely into the hole with a small
screwdriver and follow it with the screw. Solid as a rock!

You'd be trying to drill 5mm out of the centre of a 6.5mm dowel. :-(

Take the whole lot back for a refund, and buy another.

It must have worked for somebody at sometime, maybe you were unlucky
with the specimen you got.

If it's still the same fill the holes with car body filler and drill
it for screws of your own choosing.

Salt & pepper with that Sir? The diameter of those is only 5.35mm, the ones
I have are 7mm and too small! The shape is different aswell. Enjoy your

That's the nearest I have seen I would never have guessed at their name
being Confirmat Screw, they are only 7mm in diameter I now need to find
something like 9 or 10mm dia. Thanks a lot.

It's far easier just to put a moderate dab of No-nails or Gripfill in
the hole, check the leg is correctly positioned, gently tighten the
screw and leave it overnight :-)

====================
I've used them ('Confirmat screws') for years and I've never heard the name
before. I hope somebody comes along with an explanation of such an unusual
name.
