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 countersunk design with TX30 recess, helix shank for debris removal and improved clamping, and a 50° deep single thread providing secure fixing with high pull-out resistance. Coated with a patented multi-layer corrosion resistant plating offering up to 1,000 hours salt spray resistance, these screws are ideal for external applications and landscaping projects. The 25° sharp point and single lead design ensures fast start and improved thread acceptance while reducing the risk of timber splitting.
