In Detail

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.

Great product - needs more sizes and bigger packs

For 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.

These screws work very well starting easily in Oak and Beech which even without pilot holes they don't split. The self countersinking head does what it is supposed to and this gives a good finish. It is difficult to tell when comparing to a rival posi drive screw but the wax lubrication of the thread does make driving easier and the torx heads means less pressure needs to be applied and the bit never slips.

So far (and they have not undergone as long a test) they are as corrosion resistant as A4 stainless should be.

The only issues are there are not enough sizes offered and the packs are fairly small so bulk purchasing will be slightly more expensive, however the reduced waste and removing duff screws should make up for that.

If you are driving the smaller sizes into Oak then do use a pilot hole, this is a general issues with A4 stainless which is very brittle and the screws easily break, especially when the head starts to countersink. This can happen with the larger sizes as well but is less common.
