Sela Washers/Spat Washers question

[gordon40uk]

Hi, hope everyone is safe and well. Could someone tell me if you can use Easydrive Timber Roofing Double Slash Point Screws 6.3 with Sela washers/Spat washers? My reason for using Sela/Spat washers is because i am using used Corrugated sheeting for a hut roof and the holes have been left slightly larger than normal and my thinking is the Sela washer is wider than the timber screws alone plus nailing to 18mm OSB. Many thanks

I think as what you are proposing is a bit of a lash up, then all you can do is have a look at them together and try it, good splodge of HB25 under each as you screw them in, as it’s just a hut I think you will just have to do a bit of experimenting.
