Rated 4 out of 5 by from Excellent value SS screws Having read the previous review I was possibly extra cautious when using these, but having just used over 1000 of these on a deck I can honestly say I didn't grind the head out on one of them, and that was using an impact driver! I did invest in a couple of Wera bits (44409) instead of using the supplied bits. Maybe that helped. I only ended up only using one of them and that looked as crisp by the end as when I started. True, the bit did tend to bind in the head of the screw but a small tilt of the driver before pulling it out solved that problem.

Rated 1 out of 5 by from I wouldn't bother I've only got about half-way through the box before switching to some other screws to finish the job. Firstly, you'd have to be very lucky to finish the job with the one supplied bit. Mine had had it about half-way through, however that wasn't why I recommend to avoid these screws. 1) Normal cross-point screws cam-out, and that's what I wanted to avoid with these, however the bit easily comes out anyhow, so this is a bit of a fail. 2) When you mess up the drive of a normal cross-point it's often possible to salvage it by pressing a bit harder on it and pushing it a bit further. When you mess up one of these the square drive makes mince-meat of the screw head, so the only thing you can do is get out a pair of mole grips. This wasted a lot of time on the job I was doing. 3) The bit has a tendency to pick up swarf from the screw heads over time. Unlike with a cross-point where you just dust it off, the square bit really hangs onto it. When it gets like this it seems like it's located in the head of the next screw but it's not, so I had to keep picking off the swarf with my thumb nail every few screws and cleaning up the head. Never had to do this with a normal cross-point. It gets pretty laborious. 4) Even when you've got it right the screw heads bind on the bit at the end of the drive so getting the screwdriver out is a right pain. I started off using a depth-stop driver, but the bit assembly kept getting pulled out of my driver, and I got bored of pushing it back in and re-adjusting the depth on every screw. I eventually switched to another driver that didn't have a depth stop so I could put more force into pulling out the bit. Still it wasn't ideal! I think these screws are an example of something that looks on the face of it a really good idea but when you actually try to use them it's not so great. I've used torx bits for frame fixings so I'm not wedded to cross-points, but I think the square drive is just something that doesn't work as well as other systems.

Rated 3 out of 5 by from They are OK but... I chose these because I wanted to try a square drive. I thought I'd share my experiences. Firstly, don't worry about only having one bit for so many screws, it will last as it's significantly harder than the screws. After a few screws I thought I'd messed up the bit, however the problem was I didn't have it 100% correctly located in the screws, which were putting swarf on the bit, making things progressively worse until I picked off the swarf with a fingernail. The bit locates pretty well once it's in properly, however when it goes wrong, boy does it go wrong, and it's out with the mole grips to get the screw out. You can't finish off a drive once it's jumped out like you can with a posidrive, it's all-or-nothing 'cos the bit makes mince-meat of the head. When you finish driving, extracting the bit from the screw is awkward because it tends to grip if the screwdriver is just a little out of true when you're withdrawing it. Assuming you have a cordless screwdriver there's some weight there and it's hard to withdraw it straight because you can't 'feel' when it's lined up. I've used posi/philips and torx drive screws in the past and not had any of these issues. Maybe others will get on with them better. They certainly look quite nice, if things like that are important to you, and have a more contemporary feel., but I don't think I'll be buying them again.
