Forgefix DS4550 Decking Screw Pozi Anti-Corrosion 4.5 x 50mm x 200

Forgefix's single-threaded decking screws are designed to help prevent splitting of boards, allowing them to expand and contract with the changing seasons with a pozi drive head making it suitable for use within decking applications as well as 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. Similar in appearance to the classic Phillips cross-head, but in fact is very different, the Pozidriv has four additional points of contact, and does not have the rounded corners that the Phillips screw has. The biggest advantage it offers is that, when used with the correct tooling in good condition, it does not cam out, allowing great torque to be applied and can easily be distinguished by a line embossed in the screw head at 45° to the slots for the driver.
