Suitable sealant / screws

Hi. Can anyone recommend decent screws for attaching roof hooks to rafters? I had either of these two in mind...https://www.screwfix.com/p/easydrive-flange-self-drilling-screws-5-5-x-90mm-100-pack/82585

https://www.screwfix.com/p/turbocoach-hex-flange-coach-screws-m6-x-90mm-100-pack/46700

The company that sold me the fittings said 6x 80mm but I will also have spacers of about 10-15mm, hence the 90mm screws.

Also what is a good sealant for sealing the drill holes. Is this any good... https://www.screwfix.com/p/geocel-trade-mate-roofers-seal-black-310ml/32561#product_additional_details_container

Thanks in advance.

For wooden rafters the coach screws would be better, the others are intended for steelwork. The sealant should be fine.

You will also find a warm welcome and a lot of installation expertise on this site.
