Re: self tapping screws for lintel
It depends upon what sort of lintel it is....
You can get self drilling screws (Tek Screws) to screw into various thicknesses of steel, from light gauge, to 20+mm thick.
Sub 3mm thick, and you are looking at coarse thread screws, 3mm+, and they become fine threads- like a bolt rather than a screw.
If you try and use coarse thread ones on thick material, they tend to shear off...... If you use fine thread ones on thin material, they screw in, but don't tighten properly.

Re: self tapping screws for lintel
If the lintel is (probably) hollow (wiggle a wire coathanger through the 6mm hole to find out) you could use toggle bolts:
It sounds like you have wall units adjacent to a window or door - so the other wallplate position is OK? And then the next wallplate is only a short distance away for the next unit? Screw the two units together once mounted and levelled, the problem side may not need much support.

Yup, that would do it!moderator6 wrote:Put a big magnet on the inside of the cupboard
If your wall unit mounting is like this, you could fix it to the cupboard side lower down (with careful measurement):
and forget trying to fix to the lintel.

Re: self tapping screws for lintel
Just to come up at the rear, the solution is a Baypole Screw. The have a drill bit tip and a fine self cutting thread, its what builders used to screw lumps of wood to steel beams.
