ACFA SCREW® is suitable for fixing fiber cement board/timber to steel
such as modular housing construction. It has a countersunk ribbed flat
head, fine thread, and drill point with wings. The wings ream a hole larger
in the cement board/timber and break off when they hit the steel. This
allows the cement board/timber to be pulled tight to the steel. Suitable
for steel up to 3mm thick.
