Stainless Steel Window Upvc Door Frame Fixing Screws Truss Head
Wafer Head Type17
1. Descriptions:
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.

3. Features:
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.
