Hey European & American friends who use tools and do building, repairs, DIY – are Robertson screws common in your area?

Are Robertson screwdrivers common in European toolboxes?

In Canada I suspect that 99% of people who have tools would have Robertson screwdrivers in their toolbox. At least the red & green (#2, #1) sizes. The more intrepid will have the yellow and black (#0, #3) sizes too.

Comments, boosts & elaborations appreciated. Wondering if I send something to European customers with Robertson screws they'll throw them away and use Phillips or Torx or something.
in reply to Ross of Ottawa

Probably about 25 years ago, my father sent a homemade box of stuff to family in the UK. A few weeks later he got a letter asking how they were supposed to own a box constructed with these weird screws.

He sent them a Robertson screwdriver by return post.

looking at screwdriver sets at the US Lowes site, I'm seeing lots of sets without Robertson heads. In Canada I would expect those same sets to include Robertson. Example: lowes.com/pd/CRAFTSMAN-6-Piece…
in reply to Ross of Ottawa

Porter’s law of second generation renos: On any given towel fixture, one of the screws will be Robertson, the other will be Phillips.
in reply to Michael Porter

@MichaelPorter I particularly like when you discover a Phillips screw that has the hidden compatibility with Robertson built into the middle.

Canadians everywhere release a comforting sigh when their Robertson slots nicely into one of those.

in reply to Ross of Ottawa

@MichaelPorter
Those are actually specially designed with the idea that you screw them in with the Phillips, so that you can't overtorque them. If you need to remove them years later, you can use much more torque with the Robertson to break through any sticky rust. My pool is constructed with them...
in reply to Martin Settle 🇨🇦

@martinsettle @MichaelPorter They really do shine for removing old long-in-place screws. Often it's worth taking a moment with a pick to clean out the corners though, so you can get a good grip.
in reply to Ross of Ottawa

@MichaelPorter And some Philips fit nicely in the Robertson holes. It feels like software emulation--good enough to use once or twice, but we'll use the real tool to do serious work.
in reply to Ross of Ottawa

I've never seen a screw head like that in Europe. I would need to order one on Amazon. Idea! You could include a screwdriver with whatever it is you're selling, like the WeFixit people do...
in reply to LillyLyle/Count Melancholia

@LillyHerself True - maybe that would be the start of a new proliferation of them into Europe.

The little item I sell can be mounted with a couple of screws and is very cheap, so I'll probably just put a couple of Phillips screws in the package.

in reply to Ross of Ottawa

It's funny, I spent the first 21 years of my life in Canada, but I have no recollection of ever seeing a Robertson screw.
What was their normal application? Can't be bicycles or electronics, or I'd have seen one, as I regularly took those things apart.
in reply to LillyLyle/Count Melancholia

@LillyHerself Lots of wood-joinery use. Pretty much all deck screws are Robertson here. They're not as commonly in machine screws, or electronics, but we don't build a lot of that domestically.

All electrical receptacles, light switches and boxes - everything behind the decorative plate really - are Robertson here. Often Phillips compatible too.

Many hinges on doors are Robertson here. A lot of us will throw away the phillips wood screws that come with anthing and use our own Robertsons.

in reply to Ross of Ottawa

@LillyHerself Phillips is pretty rare in the UK. Pozi is by far the most common for woodscrews, with Torx a rising second. I don't think I've ever seen a Robertson in my life.

I suspect Europe is the same, maybe more Torx and less Pozi.

in reply to Ross of Ottawa

I'm in the UK, but I've been seriously considering making my own screwdrivers. Mostly so I can have stupidly long ones.

While those wouldn't be much use, I don't think I've seen them outside of construction, I've got to appreciate the ease of machining. I think I could manage one of those with a bench grinder. A Phillips? Not so much

in reply to Emily S

@Emily_S True - that's appealing in a pinch, to be able to grind one down.

The only grind-your-own screwdriver I've had to make was a crazy equilateral-triangle socket heat a little while ago. I think it was on an espresso machine. I ground a nail into a triangle and mounted it in a dowel, and it worked very nicely.

Had never seen those screws before or since.

in reply to Ross of Ottawa

euh the things they invent to try and keep people out of kitchen appliances. The notched flat head is so common my local repair cafe has one we made in the communal toolbox.
in reply to Emily S

@Emily_S Ugh, those things. I dealt with one using needle nose pliers once but thankfully haven't had one around since. Hope it stays that way!
in reply to Ross of Ottawa

anything I build that is NOT wood is usually fastened with hex socket cap screws, whih are of course manipulated with Allen keys. I'm Canadian, and would find Robertson screws in non-woodworking, non-home (electrical, etc.) things weird.
in reply to anotherandrew

@anotherandrew yeah, my application needs a wood screw to affix an item to a wooden cabinet. For screws into plastic cases or for circuit-board standoffs I pretty much always use torx M3 or M4 these days
in reply to Ross of Ottawa

in that case yeah I’d expect a Roberson screw, but your poll and the general comments seem to indicate a Phillips screw is probably the way to go internationally.
in reply to Ross of Ottawa

they will. I have a full set of Robertsons which have moved from Berlin to Munich to Boston and not been used. I asked a few people in Germany and none had heard of them.
Use Phillips or include a driver
in reply to Ross of Ottawa

I have No2 Robertsons screwdriver bits for my drill and my driver handles. I acquired these because they are beginning to appear in general use and in appliances that I repair at #RepairCafe.
I need to get hold of No0, 1, and 3, but they seem rare and expensive.
In the meantime I grind my own as needed.
I am in the UK
in reply to Ross of Ottawa

I see a lot of torx and pin torx, and I have a full set of micro and standard torx drivers.
For day to day use construction adn woodwork screws I use torx if I can, though I end up with Pozidrive of hex for stainless steel.

I am also seeing a lot of triangular, Y and triwing screws, so have a set of them too.

I used to have a System Zero driver many years ago but have lost it. I could do with another one as these are appearing too!

in reply to Ross of Ottawa

I think a welder would be more effective. The domed head is very hard, if not impossible, to grip with vice grips.

The ones I have seen have been in recessed holes in plastic appliance casings, so absolutely no non damaging access to them.

in reply to Ross of Ottawa

I can turn any head into a slotted head if I can find the dremel tool or a hack saw blade.
in reply to Ross of Ottawa

@antares
It would be if it is a surface fixing.
The ones I have come across are in deep tubular recesses in plastic.
The one that wasn't was still difficult and would have needed a Dremel cutting disc to get at as it was in a hollow under a toaster.
in reply to Alfred Chow - Maker of Things

I am now wondering how much it would cost to have a full set of handled drivers, and hex shaft bits sent over.
in reply to Alfred Chow - Maker of Things

@Maker_of_Things Don't know if they ship internationally, but Canadian Tire or Rona would be where many of us would go if we needed a replacement:

canadiantire.ca/
rona.ca/en

in reply to Ross of Ottawa

I shall see if they do, and if not see if someone in Canada can send some over. I know a couple of local Canadians here, one is heading home soon so I could ask.
in reply to Alfred Chow - Maker of Things

@Maker_of_Things That's probably the best approach. Shipping to UK is often uniquely expensive from here for some reason.

If a friend gets some on a trip, you should caution them to put them in checked baggage, as security will confiscate any tool items in carry on. I lost a nice compact multi-driver that way once, in the early days of airport security paranoia.

in reply to Ross of Ottawa

I could say 'well I used to live in Canada at least' but I think all the Robertson bits I have, I acquired after moving back to the US (a number of them in a brand-new DeWalt bit set, which I mostly bought because I needed more slotted and phillips bits that weren't totally trashed)
in reply to Ross of Ottawa

I'm one of the odd people outside Canada who has one.

Between my grandfather who did woodworking and airplane maintenance, a father who did automotive maintenance, and my own work, I have collected an odd assortment of screwdrivers.

That being said, I don't know where I would go to find a Robertson screwdriver if I wanted to buy a new one.

@ottaross

in reply to Ross of Ottawa

I have Robertson bits.... and I fkn HATE them.

I only use them if I cannot avoid it.

in reply to Ross of Ottawa

I'm sure we have something of the sort on the back porch or in the garage, dunno about specific brand.
in reply to Ross of Ottawa

I wonder if you did the poll asking about square drive to US users if you’d get different results.
in reply to Jon_Alper

@jon_alper Possible. My focus was Europe really, for work-related intel, but was glad to see some informative US-based feedback too.
in reply to Ross of Ottawa

American here but I have sets of them around. I've done enough work to know I'll run across them. I prefer them for deck screws but torx is mostly what you find here. Sometimes they're dual bit which is awesome.
in reply to Ross of Ottawa

No. But I can tell you what other types of US bits can be used to turn one of those....
in reply to Ross of Ottawa

Almost unheard of in the UK and Ireland. You'd see the heads in standard screwdriver sets but I've never once seen an actual screw in use. Pozidrive is standard.
in reply to Mike Morris

@MikeMorris Aha - good to know. I think the Pozidrive is mostly Phillips compatible?
in reply to Ross of Ottawa

Canadian, as you know. I can't imagine a life without them.

This book has interesting info about them (and all screws really) amazon.ca/One-Good-Turn-Natura…

in reply to Camerondotca

@camerondotca Indeed - they really do seem superior to the alternatives. Such good grip, and excellent hold on a bit without falling off when you're reaching to drive one in with one hand.

@Catelli Ha! Sounds like lots of kindling created.

@david_megginson As the patents expire, I suspect the uptake will catch on internationally. Hard to not see the benefit once you've used them.
Unknown parent

Ross of Ottawa

@yngmar Oh absolutely we're enthusiastic about them.

A Robertson screwdriver and a buttertart can get us talking for hours.

Phillips are very common here too, as we're so near to the US, so I'd likely provide those with my item for Euro customers.

in reply to Ross of Ottawa

They are rare here (Austria, Europe). People would probably assume that such screws were used intentionally to keep them from disassembling the thing. 😁
in reply to Ross of Ottawa

No, they’re not at all common here. Specialist socket set stuff really.
in reply to Ross of Ottawa

A friend who was a seafarer gave me some.
Here they are so uncommon I use them as "antitampering" screws 😄
in reply to Ross of Ottawa

these screwdrivers are so poorly named. Should definitely be named by shape for idiots like me who can never remember and end up just calling them “square”, “x”, “flat”, “hex”, etc.
in reply to Rob Attrell

@robattrell that would be a step forward for broad understanding. Maybe a new open-source of the screwdriver world.
Unknown parent

Ross of Ottawa
yeah it's really caught on here. The effectiveness is pretty convincing I think, once you drive a few into a piece of wood.

@EricCarroll handy for tiny #4 wood screws!
in reply to Ross of Ottawa

I’m in the US and had to look up what “Robertson” is… I call this “square drive”. Bad education, maybe. They seem to have become much more common, especially in carpentry.
in reply to Ross of Ottawa

Before I even thought about immigrating to Canada, I read an article about the advantages of "square drive" screws and built quite a few things with them.

Maybe I was destined to move to Canada?

in reply to Ross of Ottawa

I also started drinking Tim Hortons before I thought about immigrating.

I was marked.

in reply to Ross of Ottawa

I do have one or two Robertsons screwdrivers bits mainly because I have quite an extensive collection of screwdrivers and bits, but Robertson screws doesn't exist at all in Europe.
Unknown parent

Ross of Ottawa
@theotherbrook Perhaps, yes – hence the picture to ensure others got the reference. Even Phillips is less widely known than I'd have thought. The Pozidriv variant in Europe seems to dominate.
in reply to Ross of Ottawa

"The History Guy" (Lance Geiger) did a fairly comprehensive background on Robertson and the Robertson screwdriver: youtu.be/R-mDqKtivuI
in reply to MJ

@wpgne It seems one could fill a library - or maybe the wing of a library - with books & videos on the topic. Great to see folks who were so inspired by the topic that they dug so deeply into it.

Hi, im not too familiar with tools but i think in germany torx screws are quite common:
