Installation
Prepare a suitable pilot hole for the screw diameter, material and thickness being fastened. Form a matching countersink so the tapered underside seats correctly, leaving the rounded crown above the surface.
Use a correctly fitting PZ2 Pozidriv screwdriver or bit and tighten carefully to avoid damaging the recess or stripping the mating thread.
