A coarse thread hex head screw with EPDM sealing washer designed for a range of general fastening applications such as fixing timber or thin steel to timber substrates, whilst eliminating the need for pre-drilling (some hardwood substrate may require pre-drilling). The Type 17 point is a sharp, fluted point offering great timber penetration and drive when accompanied by a coarse biting thread, ultimately allowing for a quicker and cleaner install. This screw is available in zinc yellow or class 4 galvanised variants, making it ideal for internal and external applications.
