How To
- Determine required fastener length by adding insulation and membrane thickness plus embedment depth.
-
Align the fastener perpendicular to the deck surface and use a screw gun with a #3 Phillips bit.
-
Drive until a slight depression appears around the plate or insulation surface; do not overdrive.
-
Ensure the plate does not spin and that the fastener is tight but not over-torqued.
-
In rigid cover board applications, monitor torque to avoid deck stripping.
-
Perform pull tests to confirm proper anchorage strength.
