Eight sizes of Phillips screw heads?

Looks like I really need more screwdrivers!!

I've given up using anything remotely like a Phillips or a Pozidrive. Seems to me, especially with the latter, that there is a distinct lack of adherence to the spec. between screw makers and driver bits. The number of times, the bit cams out....so it's Torx for me every time now.

My b.i.l. a (English born and trained) joiner now teacher in NZ told me they use virtually exclusively square drive. I knew there were loads of heads, but didn't realise there are quite so many.

I've been using Wurth's AW Drive screws for a while now, it's a sort of mix of Torx and Hex which works really well.

tool station did a range of paslode (I think) tori head screws a few years back. well priced and decent quality, but sadly they seem to be discontinued everywhere now.

the robertson is genius didn't realise there was this much choice

 

[Phil Pascoe]

No, I didn't either. I came across that page looking for information on something in particular and was surprised by the sheer number, that's why I thought it worth posting.

While talking about screws, it's worth me re-iterating that the Bullet screws from Travis Perkins are to be avoided at all costs if you use an impact driver. They snap very easily.

 

[Phil Pascoe]

While we're on the ones to avoid, the budget screws from Toolstation have heads formed from cheese

I think I must have screwdriver bits to cover most of those in the wikipedia article since I bought a box of several dozen including security screw heads several years ago.I think I have used five of them and two were torx.I find it curious that every plain slot head bit in these kits is very thick in relation to it's width but I suppose that comes from making them from 1/4 inch hex.

It has been a minor annoyance for years when people ask me if I can lend them a Phillips screwdriver because they have a screw with a "star" shaped recess.It isn't so much that I dislike lending tools to people-although I don't appreciate it if they take ages to come back-its rather that true Phillips screws are fairly rare in the UK since woodscrews tend to be Pozidriv and the head geometry is different.What I hadn't realised is that JIS heads look similar and have very different geometry and this image shows just how different.

I had to buy a set of JIS screwdriver for working on cameras and lenses.

FWIW a JIS driver works great on a phillips screw but a phillips driver is terrible on a JIS screw.
