I would use a 45 or 50mm but check as much as poss that you wont hit any services etc.

As a rule of thumb I always you a screw at least twice the thickness of material I'm fixing.

30mm are ample, just dont sink them to much, cable and pipe runs

definatly no more than 30 12x20 or 22 is only 2 or 4mm to spare before penetrating through the floor

Do you actually mean that you are using a 30mm length screw but need to know the width of screw?

8 guage, or whatever system of sizing thats used these days!

Trust a woman to think of width not length!!

I couldn't understand why you'd given the length and still needed to know the length, and I'm not the expert.

Thanks for reply's, used 30mmx4.5 and they worked a treat. Cheers Steve

Steve,

Glad that was sorted out was that an equivalent to a number 8 screw then?

That's what would be handy on here, a table of equivalent screw sizes, it'd make choosing easier.

I think so, but your idea is good for sort of beginners like me. Thanks again.
