Rated 5 out of 5Â by NumeniusAqua 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!
Rated 2 out of 5Â by HouseDoc 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.
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!
