Rated 5 out of 5 by Exceeded my expectations These were cheaper than a branded box featured on the same page, and I did wonder if the quality would suffer, but there was a considerable price difference so I thought I'd give it a punt. I am glad I did. These went in with no pre-drilling and were used to fasten 18mm outdoor ply to the steel chassis of a horse box prior to an aluminium floor going over the top. They self-tapped into the steel chassis and box sections no problem. Drilling a pilot into the wood made it a little easier and is the work of seconds. As they were so cheap and so easy to use, I will be using these for other jobs in future where I might have drilled and bolted. Very pleased! 2 Jul 2014
Rated 2 out of 5 by not happy with this product i was using 40mm self drill fixing and run out so i bought these and realised that the drill tip was very long which in turn means a shorter thread on the screw which caused me problems. 29 Oct 2013
Rated 5 out of 5 reliable self tapping screws Very good screws, for a good result better to pre drill, although they are meant to do it, they do,... just! 1 Aug 2013
Rated 5 out of 5 by Decent Heavy duty fixing I used these beyond their specification in that I was fixing down 18mm plywood sheets to a checker pattern mezzanine floor. Worked very well, even though I should have used the longer ones to fix, all I had to do was let the ribbed head bore it's way into the plywood. Just wish they were a bit cheaper as they only come with 100 to a box. 22 Dec 2012
