There's seems to be a UK wide shortage of the 64mm Kreg exterior grade pocket hole screws, including the bigger HD screws so I need an alternative for fixing 2x4's.
I've already got a load of 50mm screws (2") but after an unglued test joint (I am planning to glue the joints though) I think they could be persuaded apart if I tried hard enough, especially when tested next to some other joints where I've screwed direct through the timbers.
I've found these Spax washer head screws as an exterior grade alternative but what size is best to order (they cost a fortune so I don't want to get the wrong ones!). https://www.toolstation.com/spax-wirox- ... rew/p37824
Firstly, do you think these would be a suitable replacement and secondly, should I go for 60mm or 80mm given the thickness of the timbers? I've attached a quick sketchup of the joints and the sizes of the screws.
Which should I order - or do you have any better solutions?
