The reliable PZ2 drive prevents bit cam-out, allowing you to drive each screw smoothly without damaging the head or workpiece. Featuring a corrosion-resistant Wirox finish, these screws are built for durable interior applications. This handy pack of 200 pieces provides everything you need to complete your cabinetmaking and fitting jobs.
