By far the best I've just had an extension built and also I am totally refurbishing my house. I have had to knock down a couple of walls and build new stud walls as well as replacing the old chipboard flooring with new so needed decent screws to get the job done. I purchased 3 different size Spax screws after reading other customer reviews on these and have to say these are by far the best screws out there. You can really feel the screw bite into the wood and no need for pilot holes close to the edge as these screws do not split the wood. Might not be the cheapest out there but I'd sooner pay the difference knowing I've got the best screws for the job that needs doing. 28 Aug 2015
Forget the rest buy the best Spax screws are the best screws to buy its the first time I have bought them and they will be my 1st choice from now on.They are top quality they have a deep recess so you get a good grip with the screw driver bit and they drive in to wood very fast every time 14 Aug 2015
A Quality product Don't let the price of these screws mislead you, just because they are a bargain price, they are not 'cheap' screws, I read that there was no need for pilot holes or a countersink hole, I thought oh yeah, we'll see, but the price sealed the deal for me, money is always tight, so I bought several sizes and gave them a try. My first trial for them was a dry piece of wood that my previous screws kept splitting, so I gave them a try, straight in, no splitting, or even a crack and they countersunk themselves, exactly as advertised! I will only be using these screws from now on, absolutely brilliant. 5 Aug 2015
The best screws I've used others over the years. These are expensive. You get what you pay for. No twisting, snapping or cross threading. And they don't go rusty 27 Jul 2015
