Hi All

Having problems with putting screws into the edge of 18mm MDF.

I've tried correct size pilot holes and special MDF screws from SPAX but I
still get splitting and a slight bulge where the screw is.

Special MDF screws are best (or least worse) but still noticeable.

Any tips?

Dave


Hi,

Have a look at the woodfit site, they have loads of fixings for this
sort of thing, eg:

Also some good tips he

If just a few holes I'd try giving the screws a good coat of molten
wax then dropping them in oversized pilot holes filled with epoxy.
After the epoxy has set the screw should home out (hopefully!) and
allow the other bit to be fastened on securely. Would need trying on
some scraps first though.

cheers,
Pete.
