The TIMCO Decking Screws Countersunk A2 Stainless Steel – 4.5 x 65 are an economic but highly effective solution for softwood decking construction. Manufactured from A2 stainless steel, these screws offer superior corrosion resistance making them ideal for multiple external applications, especially decking platforms. The double countersunk head reduces the likelihood of head shear and assists completion of countersinking, while the helix shank removes debris and improves clamping. The single slash point reduces torque and minimizes the risk of timber splitting at low edge distances. These screws are essential where corrosive environments exist or when working with materials that have inherent corrosive characteristics such as Green Oak.
