Rated 1 out of 5 by from Useless Like others never felt compelled to write a review before and generally found quality sold by Screwfix to be very good. However, out of the first 8 screws I tried the head sheered off 6 of them with only a minimal torque setting on my drill. This is a problem that seems to have been experienced by quite a few others. Should have started with reviews from low to high....

Rated 2 out of 5 by from OK, but be careful! I found these screws, including shorter versions, prone to snapping in older harder wood in which I had previously drilled pilots. This is frustrating as they snapped at the start of the thread which by then was just below the surface of the wood so can't be withdrawn - means repositioning and redrilling. I still found them snapping even when lubricated. As a long-term DIY-er I regard this as an ongoing feature of stainless steel. But when they're finally in they'll be ideal for anything the climate throws at them!

Rated 4 out of 5 by from High speed screw Smooth and fast to use. Excellent outdoor screw with good strength. A bit pricey but totally reliable. Great for most projects.

Which screwdriver bit?

Using an Erbauer 18v impact driver, which type of bit do I need for driving in the turbo ultra stainless steel woodscrews with a prodrive recess? I have over 500 screws to fit and want the correct spare bits.
Asked by: Purton

Is A2 stainless steel suitable for screws to be used outside? Or what stainless steel screws should I buy?

Asked by: SvTT
A2 stainless steel is suitable for outdoor areas not close to the sea, as A2 is not suitable for non freshwater areas.
