Can we all just agree that we have too many screw heads already? Like, can anyone give me a good, solid reason why we need Pozidriv AND Supadriv? More to the point, is there a good solid reason we need that many different cross drives? I mean, I get that some (like Frearson) are irrelevant unless you work on vintage Chris Crafts, but seriously... this is ridiculous.
Again, my preference is Pozidriv. Maybe it's because most of the equipment I see it on is of exceptional quality (Turbosound, XTA, MC2, BSS, Quested, etc), but I always feel like it's a better design than Philips.
Went through all of them and I can honestly say I have seen 75% of those. It helps when you have a buddy in the fastener business, specializing in security units.
Well I don't know anyone in the business, but I had many opportunities to study the various types of security hardware back when I was drinking & passing out in men's room stalls a lot.

The ones I really HATE are those damned combination types - Phillips/straight, Phillips/square, etc. They don't work worth a crap with either type of driver! Grrr. And the hardware stores seem to think they're the greatest thing since candied yams - sometimes it's all they have in stock!!

I had a chuckle skimming that Wiki article - apparently now there are actual combo driver blades out there that fit into all the various nooks & crannies of these stupid combo fasteners! Has anybody seen one of these? I'll definitely buy one if I ever find one in a store.
I used to work on a lot of Compaq (computer) gear back in the late 90s early 2000s. All of the screws (at least on the desktops and servers) were combination Torx and slot, but the slots had sides so they still worked very well indeed in case you didn't have a Torx handy. I never had problems getting them undone or with them stripping. Honestly Torx is amazing. Loads of torque, easy to home, basically impossible to strip, and they don't "jam up" like robertson or allen.
My pocket jigs both use the square drive screws and to tell you the truth I curse those things every time I use them.

It has a few issues I can take care of. Carbon crank arms, wireless shimano dia2
Carbon wheels
MSRP in 2016 was 12.5 K

those damned combination types -
There is a little known one in that mix, as it isn't a combo. A #2 Robby fits a regular #3 Phillips quite nicely in a pinch.
Well, if you're getting into tips, a terminal-block sized flat blade usually fits a Robertson cross-wize, for you guys that have done instrumentation work.
I thought Torx was OK until junkyard hunting. Now I know better.

Nice! I crash too often for carbon.
100 yards of Sufix 832 10lb braid for end of season fishing.
8 pieces of FR4 0.090 unclad PCB to shift projects off the test bench.
I bought in some AD876JR A2D converters for a project from China.
They actually work !
I have had problems with Chinese chips's in the past but these are fine and very cheap.
Was worth a punt.

They do break dont they ?
The Cannondale CAAD 12 alloy is getting some rave reviews and considerably cheaper as well !
The History Guy on Youtube spent some 15 minutes to explain the various Torxes and Robertsons:

It usually works even better, in my experience. I typically favour the mismatched combo. It will strip if pushed too hard, but not any worse than the Phillips on Phillips.
To avoid confusion:
A hex head screw uses a socket to fit over it and an Allen head uses a hex key to fit into it.
Jim, I think you described a Pozidriv head.
EDIT: Nope, I see ACR is different. Can't say I've ever seen that. Looks like Phillip's answer to Pozidriv.
Haha I agree Cal, I never call Allen's a Hex, but our fastener supplier doesn't call Allen's allen.
So, perhaps, it's just another one of those transatlantic differences in terminology? (I used to think Allen's were British, bit I think I was mistaken and they're of US origin)
Either way, fastener quality in general is poor in a modern world. (I have 70 year old Whitworth that are still like new, and not chewed up)
They market them as "hex keys" here...

Went thrift store shopping with my wife. I always head for the electronics or the records. Browsing a lot of old Polka LPs I noticed two "albums" on the bottom shelf. Turned about to be albums full of Jazz CDs.
Plenty of Duke Ellington, Oscar Peterson, Charlie Parker, George Shearing, Sonny Rollins, Dave Brubeck, etc, And 1 Loretta Lynn. 🙂
Total 91 cool CDs perfect for me. $6.

Yes, we are on the same page. Confusion has arisen in the past on construction sites when Allen screws were brought in lieu of hex screws. Not gonna workie.The generic name for "Allen" is internal hex drive
AFAIK, there's no such thing as a DD galvanized Allen screw. 😉
