Thank you for your enquiry, whilst the plating on Screw-Tite 2 is to a high standard, we classify it as an indoor use screw. For this sort of project, you would be better with a screw from our Deck-Tite or Exterior Tite range, both carry our Net-Coat plating specifically designed to reduce corrosion caused by exposure to the elements. For maximum protection, you may also consider our Deck-Tite Plus range of stainless steel screws.

Thank you for your enquiry. Whilst the coating on Screw-Tite®2 performs to a high standard, they are what we classify as indoor screws. If they are being used internally within the shed's construction with little exposure to moisture, they will be suitable. However, for the size of screw you are requiring, we would recommend our Deck-Tite® 4.5 x 57mm or 63mm screws which carry our Net-Coat® plating, designed specifically to prevent corrosion from exposure to the elements. You could also use the same sizes in our Deck-Tite® Plus range of stainless steel screws for maximum protection.

Thank you for your enquiry, Screw-Tite 2 would be suitable for use in this application.
