These single threaded Decking Screws by Forgefix with Pozidriv heads and are specially designed, hardened and green treated. The screw is designed in a way which helps prevent splitting the boards, allowing them to expand and contract with the changing seasons.

They are specifically used in decking installations but are also widely used in exterior timber and fencing applications.

The 1,000 hour green treated finish offers excellent corrosion resistance to ACQ (Alkaline Copper Quaternary) treated timber used in construction and decking applications.

Although the Pozidriv screw is similar in appearance to the classic Phillips cross-head, it is in fact is very different. The Pozidriv has four additional points of contact, and does not have the rounded corners that the Phillips screw drive has. The biggest advantage it offers is that when used with the correct tooling in good condition it does not cam out, allowing a huge amount of torque to be applied. The Pozidriv screw can easily be distinguished by a line embossed in the screw head at 45° to the slots for the driver.

Single thread screws have been designed to offer higher pull out values and quicker insertion.

Features:
