Hi All

Looking to fix some 8x4ft 18mm OSB board on top of my flat roof ready for fibreglassing by a friend.

What are the best screws to use ? They need to countersink in and not come loose/free...

Cheers

bilabonic,
Use spax screws they will self drill a pilot hole and will self countersink the ply.
