Putting up a shower screen today. Foolishly decided to use the fixings supplied. Have a box of bits drill silicone blah blah etc. But do i have a PH2 bit in my bit box.. do i hell...have bought some new ones

And that my friend, is what they call, life.

As the saying goes, **** happens, deal with it.

Indeed blasted the screws in with a pozi bit, the horrible chattering sound had my teeth on edge. But hey ho.

Weellll, as long as they come out, just mark it down to experience, and then ignore it.

Most of the time it's better to chuck whatever they gave you and use some screws that actually have holding stuff as a selling point, not minimum cost to the manufacturer of some other item!

I agree complete I usually do chuck the rubbish supplied fittings away. But not this time

Maybe China hasn't caught up with pozi yet - still uses phillips ( maybe the patent's run out )

That's the only one I could find to hand, not sure if it's genuine though?

I don't know why we don't all use square or hex screws. I'm sure they don't cam out like Pozidrive and Phillips do.

I use torx one from screw fix a lot. The trouble the head designers have is they can choose between not camming out or the screw fitting on the end of the bit securely. Also the square and hex put all the force in a week place on the screw and they don't want to make the screws out of expensive material. It's quite a complicated business of tradeoffs I realised

 

[EddieM]

Well the a4 stainless torx screws I bought for the job should turn up tomorrow now that's what I call quality project management

Yes, I'm sure that a lot of research has gone into the design of screw types. I suppose that another advantage of Pozidrive is that, unlike torx, it will allow a slight leaning out of perpendicular of the screwdriver in relation to the head of the screw.

Actually it's the other way round - pozi is very intolerant of lean compared with torx. But the torx fall off the bit easily

I hadn't realised that. Looking at the torx screwdriver bits, the hexagonal part seems to be parallel along its length, and I assumed the screw head would be the same.

Is it the case, then, that torx bits can cam out easily compared to Pozidrive?
