Type D/P Lath Head Drill Point are designed for attaching wire lath to metal studs 20-12 gauge.
Self-Drilling Screws, also known as Tek screws, eliminate the need for a pre-drilled hole. The length of the drill point determines the material thickness which the screw can reliably penetrate. When selecting a self-drilling screw design, it is important to consider the material thickness and type of materials to be joined. These stainless teks are great to use in environments that are damp.

Self tapping drill point is designed for penetration into heavy gauge metal Wafer head provides a greater bearing surface with a low profile head exposure Heavier shank ensures entry in clips of hard steel Also available with ultra fast drill point
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 Wafer 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.
