Just the job All in all a great value screw that wont rust, makes it great for exterior application, as long as you use the correct fitting bit to match the head you wont mangle the head of the screw, self countersinking and easy start with very little splitting without piloting 27 Jun 2015
Used to be good, now poorer Screwfix's Turbo Ultra A2 stainless screws used to be amongst the best and great value for money. I've used them extensively for many years on all sorts of construction projects. Sadly the most recent batch of SKU 10078 3.5x40mm supplied in June 2015 are made from a new alloy. Through extensive testing and wastage of approximately 1/2 of each box I have concluded that the new alloy is a mixture of tin foil and cheese. Care must be taken with all stainless screws when driving them to avoid cam out which damages them easily but these new improved versions are ridiculous. You can snap them in your fingers (wear gloves as they are sharp). I bought some other sizes at the same time which were fortunately still made from actual metal, but the SKU mentioned above were all beyond useless. You can tell the new alloy easily if you have two batches to compare as they are significantly lighter than the older ones and are of a dull finish. Visually and to the touch they resemble aluminium screws but they box still states A2 stainless steel. As they are not cheap, if you find yourself with a box that matches that then do yourself a favour and take them back for a refund before wasting your time and then having to do the same anyway. 24 Jun 2015
Good Value Good Value for money, but some time the head get damaged easily. But Most of the time it is fine. 25 Jul 2015
The Silver Surfer . The Turbo Ultra worked excellent on my old fence repairs . With its easy start tip and its no problem ability to countersunk it made the job easier . Also due to being corrosion resistant the old fences could last another ten year . 5 Jun 2015
