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