Sorry couldn't give you a definite answer ..but I have bought screw with adapter in but not from Amazon. **Q: Is there no other waterproofing to the sheets apart form fitting together and using the washer hex screws ?** A: No, just screw them together with the screws. The washers on them seal the hole made. don't over-tighten and warp the panels though. **Q: Are these suitable for fixing an advertising banner to an external wall** A: These Screws, in various sizes, are made for fixing sheeting/cladding to timber framing and ideal for that too, as for fixing panels to a wall [brick/concrete???] I haven't used them for that, but I would think if you drilled a suitable sized hole, used a correct sized rawlplug they would be ok... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Self tapping roof screws *by G***K on 31 December 2025* All round good product ### ⭐⭐⭐⭐⭐ Very good *by A***R on 29 November 2024* Does enable what it says.
