A4 (also known as Marine Grade) stainless steel contains a small amount of molybdenum, which creates a particular type of steel having a much higher resistance to surface corrosion when compared with standard A2 stainless steel. The screws have a Torx head ensuring the virtual elimination of 'cam out', where the screwdriver is liable to slip under pressure, damaging both the screw head and the bit. Screw threads are also wax lubricated for almost effortless driving into most timbers. These screws are suitable for all outdoor projects such as garden furniture, timber framing, sheds as well as boat building and renovation. Boxes of 200. Except 5 x 60mm wood screws which are boxes of 100.

Not sure I'll go back to pozi/philips headI bought these screws because I was after stainless steel screws, not because of the Torx head. However I am a convert to them. Absolutely no slip of the driver bit in the screwhead which allows for one handed screwing in. The only downside is that I bought a box of 10 T20 bits and I am still on the first one after 200+ screws (not something you could claim with a PZ2 bit). Not sure when I am ever going to use them all up.

Great product - needs more sizes and bigger packsFor the past few years I have been a great fan of Screwfix's stainless turbo ultra screws which have posi drive heads, following a blog comment response I gave these a go.
