I would prefer the steel screws, you can get plastic plugs to seal the countersink in the rail but check on the engineering drawing for your profile rails to see how deep the countersink is.
Ha - now there's the joke!!

There is no engineering drawing for the profile of the linear rails, I had to use a digital calliper.

I did check on the sellers website - i could have checked and used others, but thought that i could not guarantee that the profile is exactly the same

There is a technical drawing for the aluminium extrusion though.

Thanks for the links
