Pull timber together and finish flush, that is what these are built for. The countersunk head self-embeds as you drive it, and the full thread grips the whole length so the join stays tight under load.

Macsim is a name plenty of local tradies already trust, and the zinc plating handles everyday damp around indoor and sheltered work. Keep them out of the weather though. For decking, fences or anything near the coast, move up to a galvanised or stainless screw and they will last far longer.

This 8g x 40mm size is a handy pick for heavier timber joins, with 25 in the blister pack and a #2 Phillips Drive bit doing the work.

Pack count and finish are in the tabs below, with the full sizing. Not sure which length suits your job? Pop in and we will line you up with the right one.
