POLYTOPS ® fixings are plastic top pins, nails and screws manufactured to a high UK standard using top grade polymer and the highest grade steel, that’s A4 marine grade stainless steel. What size polytop pin ‘head’ size should I buy to fit on 2x3 metre length fascias on my garage please? I have fixing points, wooden beams every 2 ft apart and wood only like to use only 1 pin on each! Sorry should’ve stated no guttering will be going on the fascias on the side. This is just for aesthetics.

We only use A4 marine grade stainless steel in our nails and pins which means they do not suffer with corrosion and therefore don’t leave rust stains unlike less materials like A2 or zinc plated stainless steel that are supplied despite this very well know problem with corrosion Having read up on it a bit more I believe the bigger heads are for fascias n smaller heads for soffits? Thanks, sorry should’ve stated fascias spec - 9mm by 150mm... 40mm pin length better option? I’m not heavy handed so should I just get 6? The head size doesn’t affect fittings does it?
