Conduit etc Installation Query

[Darkness]

Not sure if this the place for this type of question but...

I want to fix some outdoor waterproof switches with 20mm conduit/spacer bar saddle's etc to steel girder posts of outdoor buildings.

This is the question, what sort of screws should I use to attach these or any advice on whats the best way. Self drilling screws would be nice but I doubt I could use those.

Cheers.

self tapping yes

Maybe you could use spring clips to attach the conduit to the side of the gurder??

Also known as edge clips.

Other than that, self tap, or use self drillers. (you can remove the rear spacer bar, and just use the saddle with 2 screws when using self drillers if the head is too big).

Cheers for that guys.

Has a drill at the end before the thread, usually have hex head.

Use with your battery drill.

So many types on the market, thin sheet to thin sheet, thin sheet to 10mm section steel etc.

It says uPVC but whats the chances of drilling into steel do you know? Would be the ideal screws I'm after.

That link is for double glazing really, the rest are good.

The others are all steel ones, for gurders, purlins, sheet steel.
