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"

Anybody Know??

>>> That's the nearest I have seen I would never have guessed at their name

==================== 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.
