The TIMCO Wafer Head Exterior Green Timber Screws are designed as an alternative to traditional coach screws for timber to timber applications. These high-performance screws feature a wafer head for improved clamping and low profile finish, with a patented multi-layer corrosion resistant plating that withstands 1,000 hours salt spray testing making them ideal for external applications. The helix shank removes debris and improves clamping while the 50° deep single thread provides secure fixing with high pull-out resistance. Additional features include patented lubrication for enhanced insertion and a single slash point to reduce torque and minimize timber splitting risk.
