Washers/Fixing for Ikea Desk Supports

[relicalpha]

Hey,

I've just made an Ikea desk from a 'Karlby walnut top' with Alex drawers - and in order to try and prevent sagging, I've purchased 2 heavy duty steel slotted channel lengths (reddit advice, seemed sensible...).

I'm stuck at how to fix these to the wood though? Thickness of the wood is 3.5cm, so I would need screws no longer than 1.75cm?

But the main problem is how I screw them in, see pics below - but I think I would need at least M12 washers for the slots, how can I get a 1.75cm long wood screw in with those? Hopefully there's a solution?

The slots are 1.5cm x 2.6cm, lengths are 1.7m i.e. full gap between the drawers.



Any advice?

Really pleased with it Might add some risers once I get a better chair, but it's a good height as is.

Looks different anyway. I’m not sure what I was expecting. Can you get matching wood effect side drawers?

I don't suppose you can get dead flat channel lengths can you? Would be perfect for running across the back of my TV wall mount so I can screw speakers either side.

Glad it worked out well
