Rated 5 out of 5 by from Fixing Zinc Corrugate Sheets I have reviewed these twice before - once favourably and once unfavourably. This time favourably as they are excellent for securing zinc plated corrugated iron roofing sheets. The screws screw acceptably but the seals are excellent bedding to the sheets and the caps fit well.

Rated 5 out of 5 by from Perfect for the job These were used to secure 10 mm thick polycarb to lengths of wood, although a tad expensive in my opinion they worked perfectly and the seal cap make a nice semi weather proof bond. Defo recommend

Rated 4 out of 5 by from Does the job and good value Works for corrugated bitumen sheets not too long or too short. Much cheaper than the ones sold by the manufacturer.

Pre drill hole size

Does the corrugated plastic sheets expand, if so what size whole would I need to pre drill to allow for expansion for plastic.

Hello Frannerhammer, We would recommend you check with the supplier of the sheeting to see if this is likely to occur. Thank you for using Q&A

Is the corrugated roofing all the same depth for the screws.

Do I have to check the length of screw I need for the corrugated roofing, mine happens to be plastic, plus the width.
Asked by: Yyyy65555
Hello Thank you for your question. yes these screw would be fine for standard galvanised roof sheets, if it is box section sheets you will require larger fixings. Thank you for using the Screwfix Q&A service

Can these be used for 4mm multiwall polycarbonate dheets

Asked by: Adhh123
Hello, Thank you for your enquiry. They could be used as you propose but care would have to be taken not to damage the sheets. Hope that helps. Thank you for using Q&A.
