A standard screwgun with a depth sensitive nosepiece should
be used to install cement board fasteners. For optimal fastener
performance, the screwgun should be a minimum of 6 amps
and have an RPM range of 0-2500.
Adjust the screwgun nosepiece to properly seat the fastener.
Worn or damaged bit tips should be replaced.
The fastener is fully seated when the head is flush
with the work surface.
Overdriving may result in torsional failure of the
fastener or stripout of the substrate.
The fastener must penetrate beyond the metal
structure a minimum of 3 pitches of thread.
