Forgefix Countersunk Decking Screws 4.5 X 50Mm Green Box 200Forgefix'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.Key FeaturesSize: 4.5 x 50mmFinish: Hardened and SpecialiGreen TreatedHead Type: CountersunkDrive Type: PoziPack Qty: 200Pack Type: BoxInsert Bit Size: No.2Coarse Single Thread ScrewDesigned for decking but also ideal for other exterior timber and fencing usesPozidrive compatible head enables higher torque levels with a reduced risk of cam outExtremely coarse thread provides increased holding power in all types of decking timberSpecifically designed to accommodate wood’s natural tendency to expand and contract.
