Here's the question up for debate:
Debate
Why would any modern product use a standard (aka flat head) screw, which requires a standard (flat head) screw driver?
Standard screws are far more difficult to use in a modern era where we have power screw drivers which spin at high RPMs. If you've ever tried this you know that a standard (or slotted screw) will quickly get off balance with each rotation which really creates a challenge. The very least that should be substituted would be the Phillips (+) type. It's much more balanced. I can see using a allen type or Torx or whatever but I just can't understand why slotted would still be used. Why are slotted screws still being produced? In my thinking they should outlaw them to save the sanity anyone who owns a toolbox. :) How many billions $$$ could be saved by such a change? :rolleyes: Counterpoint? Anyone with a counterpoint on why slotted is still valid?
A better question is, why hasn't everyone adopted Robertson. Superior to both; invented in Canada; apparently "banned" in the US; something to do with "not invented in the US" I think.

Notice that all the screws in a mechanical wristwatch are slotted. There is a reason for this. The original Phillips driver was designed for building aluminum aircraft. It was designed to cam out before the material being screwed into was damaged. Later cross-drive screws, e.g., frearson, were mostly not designed to cam out. As others have said, with cross-drive screw heads the bit is self-centering. It isn't with slotted screw heads, but the slot is easily restored. If you ruin a cross drive head you need a screw extractor. All the above are much inferior to Torx.

These things must be considered! :laugh: And, I'd have more if The World would standardize on one screw type. :rolleyes:
A plain-old bread-knife can replace a flathead or slotted screwdriver in a pinch, therefore making as the standard, in my opinion.

Do you mean "Phillips", or "Posidrive"?
I knew whatever I called phillips and slotted that someone would mention some other name. I did my best to look it up but it seems a lot of people refer to them as phillips. This is a good article / video: Quick Tip: Know Your Screwdrivers (Hint: It's Not a "Flathead!") | Make:[^]
Pozidriv is not just another name, it is a very different head compared to Phillips. You cannot use a Pozidriv bit on a Phillips head and a Phillips bit on a Pozidriv screw very easily starts stripping. Sometimes wikipedia is the way to go... List of screw drives - Wikipedia[^]

My main thought is that for every other type of screw, you need EXACTLY the correct size of screwdriver. So, for a general life, you need 6-8 sizes of Phillips, 8-10 of Torx, 4-6 of Robertson, but you can by with about three flat blade screwdrivers (small, medium, large). Specifically, in electronics, NO, I can think of no reason for a standard screw.

We use slotted screws on some products because it is easier to remove contamination & debris in the field.

Ah, yes. Hadn't thought of that. Getting debris out of the slot is a simple wipe to one side or the other. While a complex shape in the screw head would make it far more difficult. Great point!! :thumbsup::thumbsup::thumbsup:

My uncle (RIP), who was a strong union man, told me that the Robertson screw and screwdriver were banished by the unions because they were "an effective labour saving device".
I'm retired. There's a nap for that... - Harvey
Thanks for that ... helps explain my continued struggle with the "irrational" (and products shipped with Phillips). (And I "should" retire; but I'm not rational either).

I find Robertson (square head) screws work best. You can put them on the driver and they stay there. Wonderful for drywalling. They are common in Canada, but do not seem to be used much in the USA. (Correct me if I am wrong).
In part, the Robertson screw didn't catch on in the US because after lengthy negotiations Henry Ford refused to license it for his cars. Re sizes of slotted screws: A pro is that slotted screw heads can be turned with almost anything, such as coins, knife blades, putty knives, tin can lids, and so on. The corresponding con is that non-commercial users rarely have a screw bit that actually fits the screw they are trying to turn. Moreover, the sides of the blade are often tapered, rather than parallel planes, with the thought that the bit can be wedged into a range of slot widths. But as a consequence of the wedge shape, the bit tends to cam out. Pro screwdrivers are sold that have exactly the right tip width for, say, the standard slot on #6 wood screws, and have parallel sides. A pleasure to use.

Thank you for your comment. The Model T was built a century ago, and one would think it of no relevance to the screws we use today. But such might actually be the case. I still prefer the Robertson because once you place the screw on the bit of a power tool, it becomes a one-handed operation. This frees up the other hand to hold things in place. If you can tell me how to do that with a Phillips or a slotted screw driver, I am very much interested. Phillips Screwdriver Versus Robertson Screwdriver[^]

Of course you can't. No doubt Robertson screws are great. However, all modern designs share the same doesn't-fall-off property, even the old Allen, with the added advantage that instead of four possible insertion angles, you get six, eight, or even twelve. If there hadn't been further advances in screw drive since P.L. Robertson, his design would be in common use everywhere. But even recently, Torx II is a big improvement over Torx.

Personally I've never heard it called standard head. In the US, every where I go, it always referred to as "flat-head". So I will call it as that. There are two situation where I choose the screws. 1. Metal work, the screws mostly comes in with flat-head (slot as you put it), Phillip, or torx. My preferences are Torx, phillips then flat because on metal all holes are predrilled. 2. Wood work, the screws come in many types. My preferences are: Star, Square or Phillip. Torx is very rare for wood. I will not use flat-head screws. I will reluctantly use Phillips if I can't find squares or stars. Aside from the crews themselves and for other purposes then what it was originally designed for, the flat-head screw driver is the most useful tool among all other types of screw driver.

Here in the Rockies-US, square are available. I preferred the star head screws, work ever better than the square. Available in Home Depot and Lowe's. Of all big box home supply stores, I preferred Menards. Sadly, no Menards available here. Next is Home Depot, then Lowe's.
