I'm glad I found this! I purchased the fasteners without the expnsion hole cutter thinking it would seal my corrugated polycarb roof better given a bigger hole in hacked through it. I'm glad too I haven't started installing the roof and I kept the Bunnings receipt for the screws. Just need to figure the water proofing of the roof against a compressed fibro. Cheers.

Hi there, glad it was helpful :) Perhaps you could use some sort of flashing for the fibro? Thanks, Kurt.

@@kitseyewitness As it turns out I'm investigating flashing along with a rubber sealant. Unfortunately it'll rain tomorrow so will have to wait it out before continuing. Cheers.

Thanks! Just trying to complete a video to release soon, and I've been trying to find the plastic screw caps I used to install my multiwall-honeycomb 8mm polycarbonate sheets, (with the rubber donut that goes under them) But can't find them anywhere!! I hope I can find these metal screws with neoprene and washers with neoprene tomorrow... Do you recommend a special screw for this or NOT recommend a particular screw, like zink or stainless? also how big should the expansion hole be? I'm having this crackling noise in my gazebo, you can watch my video to see what im talking about. when its sunny or sunny and windy, the crackling is bad, its not super super bad like ive seen in some videos, but id like it to be 100% quiet. I'm hoping its just the screws, but im also reading it might be because I didn't put anything like a tape between my polycarbonate sheets and my purlins. Could that be it? I know theres a few screws that are on there too tight, and I know I made the screw holes the same size as the screws, so these are the two things I'm trying to tackle and fix before releasing my polycarbonate roofing video to show people what NOT TO DO. Thanks for your help. Also, if you wanna be featured in my video as the expert and give me some pointers or recommendations, I'd be happy to discuss!

Hi Mateo :) Hopefully you found some suitable screws for the multiwall. You need something with a large metal washer and then a neoprene washer underneath. And since it's outside it needs to be either galvanized or stainless. Either one is fine. Stainless will last longer, but galvanized will last longer than the sheets anyway. In terms of cracking, there are a number of causes. One of them will definitely be the screws not having an expansion hole. You'll need to drill a 12mm expansion hole first (about half an inch). Also, the screws may be too tight. The second thing might be no room for expansion in the joiner. Is there a bit of a gap for the sheets to move in that joiner? Happy to help out on one of your videos :) I'll DM you.
