DIY Filing cabinet fixings help

[Swordbroad]

Thinking about it those Black connecting blocks might be ok. Could get some black screws or some b,ack screw caps.

What size screw would be best for those? 4mm dia , 20mm long and countersunk? Or 25mm.

These look a bit more slick that the normal ones Ive seen.

From time to time I do a job where the various finishes on the screws are not suitable. Usually a colour issue. I find that getting the right size screws and screwing them into a some scrap wood and then simply spray paint the heads. Lots of colour paints around for applying to metal. Then do the fixings first with an ordinary unpainted screw and if no problems getting it in just replace it with the painted ones.

Whilst thinking of painting it also occurred to me you could fit a batten across the sides full length with rebated slots on the underside to trap your rails. Paint the batten whatever colour you like, either to compliment existing or to contrast. (Remove for painting after trial fitting)

That's a great solution!

Just to add, I've used pipe clips to hold my net curtain rails in place (15mm dowel, 15mm clips), and that doesn't move at all (although it is wood, more friction). If that arrangement did move for you it's nothing some insulation tape wrapped round the rod wouldn't cure. The one in pic is a Talon 15mm pipe clip. 8mm is a micro-bore size I believe, so you could perhaps find similar pipe clips for 8mm. I know they do 10mm ones.

Cheers for all the help, first time poster so really appreciate it.

I've gone for the modesty blocks in the end, despite dismissing them initially, they are quite a neat solution. See picture of how it looks. Drilled an 8mm hole and the rods are nice and snug, just need to get some black screws and I'm set.
