The TIMCO Wafer Head Exterior Green Timber Screws are designed as an alternative to traditional coach screws for timber to timber applications. These 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 a TX30 recess, single slash point to reduce splitting risk, and 25° sharp point for fast start and improved thread acceptance.
