Hi Karen
If you’re screwing to Kingspan type insulated cladding then these composite screws are very good. They come in a variety of lengths to suit the thickness of the cladding. The cladding only has a thin foil of aluminium front and back and these screws mean that your load weight is distributed over the full thickness of the panel and both the front and rear skins of aluminium.
Cheers

If the screw head will be seen, I prefer self-drilling with a coloured head version, instead of a Tek Screw with a coloured cap.

Hi Karen
As the others have stated, there are different types and lengths of Tech or Tek Screw available.
They really are an “all in one” type of fixing to metal buildings and framing.To keep it simple, I have attached pictures of 3 Screw Tech Screws.
- The one with the OPEN threads and Spade Tip are used for drilling into general thin steel and aluminium.
- The one with the TIGHT threads and Spade Tip are used for drilling into hard steel frames and beams. (Do not use on general metal cladding buildings or alloy)
- The one with the OPEN Threads and Pointed Tip, are for drilling into wood.
If drilling into SOFT metal cladding, these can be great to use to get a stronger fixing but you require drilling a 3mm pilot hole first.

Also, regardless of the tech screw you choose. You are going to need a Tech-Bit to drive the screw.
You can buy these screws and the bits from Amazon, Screwfix, Toolbase etc.
