4. Installation Guidelines:
Use a standard screwgun with a depth-sensitive nose piece. Suggested screwgun specification for optimal performance – 4 amps minimum and RPM range of 0 to 2,500.
The Hex head is fully seated when the head is flush with the work surface.
Overdriving may result in failure of the fastener or stripout of the work surface.
The fastener must penetrate beyond the metal a minimum of three thread pitches.
