ForgeFix Single Thread Decking Screws (Green Anti-Corrosion) - 4.5 x 50mm (1000 Pack Tub) (DS4550T)
Tub of 4.5 x 50mm timber screws designed to firmly fix decking boards in place whilst also allowing the wood to expand and contract with the seasons.
The single thread of these screws leads to both quicker insertion and higher pull out values in low density materials such as timber since the structural integrity of the material is maintained within the wider pockets of the thread resulting in a greater holding power.A pozidriv head means that these screws can be driven in faster with a reduced chance of a cam out since the pozi cross-head grips better than other head shapes.Finished with a green treatment to provide more than 1000 hours of corrosion resistance to ACQ treated timber (Alkaline Copper Quaternary) which is commonly used for decking and timber construction.
