Good Item Good strong screws. Needs a bit of speed with the driver you're using as our 10.8 impact driver struggled a bit, our 12v Milwaukee one was perfect. 12 Dec 2014
Excellent screw Just to prove that most things have an alternative use I used these screws (with the aid of some soft washers) to fix my Truckman top onto my pick up!! Self drilled themselves effortlessly into the side of my truck, I'll be using a couple to put my number plate onto my new trailer too!! Excellent!! 8 Nov 2014

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
