AnchorMark HS Decking Screw 5.5 X 70mm 304/A2 Box of 500

The AnchorMark decking screw is 316 stainless steel, provides excellent weather resistance and features a grooved shank for enhanced holding strength. Its self-drilling tip simplifies installation, while a small head diameter and underhead pockets ensure that the head can sink cleanly and evenly. The drill tip also protects timber from tearing or splitting during use.
