Product Description

Introduction
A Pozi Countersunk Head Nail Screw is a type of fastener that combines the features of a nail and a screw. It has a Pozi drive head, which is a cross-shaped impression that allows for better torque control and reduces the risk of cam-out (slipping) compared to traditional Phillips head screws. The countersunk head allows the screw to sit flush with the surface of the material, providing a smooth, snag-free finish. 
ApplicationsBuilding Insulation: Primarily used in the installation of thermal insulation systems in residential, commercial, and industrial buildings.
External Wall Insulation: Often used in External Thermal Insulation Composite Systems (ETICS) to fix insulation boards to external walls.
Roof Insulation: Suitable for securing insulation materials on roofs to enhance energy efficiency and thermal performance.
Floor Insulation: Utilized in floor insulation systems to prevent heat loss through the flooring and improve overall energy efficiency.
