This screw is mostly used on timber-to-timber connections and fireproof insulation boards. It consists of 4 parts: hex washer head, chip board thread, 3 flutes on thread, TY-17 cut point/TY-168 cut point. The length can reach up to 16”.

Key Features:
* The die is precisely made with a raised hexagonal head, which provides a stable driving-in process and a concentrated downward force for the screw when using the socket.
* 3 flutes on thread and TY-168 cut point help reduce driving torque, improve cutting efficiency, and reduce damage to building materials.
* A leading international standard of distortion.
