    Default Galvanised 20mm screws for scyon cement sheet

    Hi I need some advice on screws to fix into scyon external cement sheet

    It is 19mm sheet which is getting screwed down onto a steel base. They will be screwed from the underside through existing holes in the steel and into the cement sheet.

    I canít find any 20mm concrete screws like tapcon but am wondering if I can use normal wood or metal screws instead.

    Iíll also be using some sika FC to glue it down.

    Thanks
    Dane.

    Not sure, but is it normal to have Scyon itself as the 'holding' material when fixing it down?

    No donít think so. Normally you go through it into steel or timber. Iím thinking normal wood screws will probably do the job.

    Alternatively I can bolt though and countersink the head on the table top.

    Oh. I thought you were using it as flooring. Do what you like for a table top

    A course thread would be best. The Sika will do most of the work
