Protip: All Ikea furniture with screws use Pozidriv heads. (Everything with bolts using Allen heads, of course.)

It's unfortunate that Ikea doesn't seem to publicize this or provide drive heads with their furniture (AFAIR). I was glad I picked some up before I did a kitchen with Ikea cabinets. It saved me a lot of grief.

I don't think they provide it with their kitchen elements, but for all furniture they provide a hex key for assembly and assume that you have a screw driver yourself.

They don't strip, or at least it would take a tremendous amount of torque to strip them. My experience has been that the driver strips before the head does.

Usually the screw snaps in two at over-torquing before either the head or tool strips.

I've had that happen a few times. It's super annoying, but that what you get when not paying for the quality screws.

As someone who has just remodelled an old house with loads of flatheads: you've got to be kidding me. I hate those things with a passion. Flathead screws only restrict the movement of the screwdriver in one dimension and allow it to move in the other one. This leads to the screwdriver to keep sliding out when you put force on under even the slightest angle. Phillips screws improve on this design by restricting moveme…

An advantage of flathead is that it is easy to unfoul the screw head. A minute with a utility knife or a flathead screwdriver will clear the channel of dirt or paint. I would not want to deal with a torx that has several layers of paint dried into it.

Break out the drill and drill a tiny hole down the centre to crack the screw. Now pull it out and can put in a new clean one.

As far as I'm concerned, torx is the only reasonable screw anymore. It seems like most construction screws (at least in the US) have moved to this. Just to make the point: I've stripped out more torx drivers than I have torx heads. I can say I truly don't understand how phillips ever even took hold over flatheads. Cheap phillips head screws seem designed to strip out. Somebody elsewhere in this thread made the point…

I prefer square drive to Torx for larger screws. But I agree with Philips... yikes.

In Canada there is a saying: Anyone who doesn't use a Robertson head is just being an asshole.

I'm astonished to learn that Robertson are a Canadian thing! My grandfather was a cabinet-maker and god save you if you used something else in front of him.

IMHO, the Phillips head is pure evil and persists mostly because it’s one of the best ways to cause consumer-induced early obsolescence in any product that requires assembly by the end-consumer. It’s a huge unspoken conspiracy in the manufacturing world: “You supply Phillips screws. I supply Phillips screws. Everybody supplies Phillips screws. Everybody stays happy (except the consumers).” “You stripped the screw hea…

I can only agree, Pozidriv is so much better! I recently bought specifically both philips and pozi head screwdrivers, and Ive generally had both before but it still a hassle to always select the right one.

Pozidriv is the devil. It's impossible to distinguish visually in many cases between Philips and Pozidriv. Just use Torx, Square, or Hex. That way there is no confusion.

Happens with the better ones as well, it's just a matter of setting the torque limiter of your screwdriver/coordless drill to match the job. Sometimes takes a few mistakes, but it's safer to start with a low setting and adjust up until you have the right torque for the screw.

If you work with wood/carpentry construction in Canada, a higher percentage of things are square drive (Robertson). They were less common until recently in the USA due to patent licensing issues.
