The TIMCO Hex Flange Head Exterior Silver Timber Screws are designed as an alternative to traditional coach screws for timber to timber applications. These screws feature a patented multi-layer corrosion resistant silver organic coating that withstands 1,000 hours salt spray testing, making them ideal for external applications. The hex head design includes a fixed washer for improved clamping, while the helix shank removes debris and provides superior holding power. With a 50° deep single thread and 25° sharp point, these screws offer secure fixing with high pull-out resistance and reduced risk of timber splitting.
