Square and Robertson are 2 different types. The Robertson screws have a slight taper to the socket you can see if you look. Square drive screws are NOT tapered.
There are also 2 different types of common cross slotted screws. One is Philips that is actually meant to be a ‘one and done’ install. It was meant to cam out to prevent over torquing when assembling something back in the day. Don’t blame the screwhead for your poor choice in application or you cheaping out on the driver to install them because you bought some crappy dollar store driver.
And then there the VERY similar looking JIS, (Japanese Industrial Standard) screws that require their own special driver. If you get Philips and JIS screws mixed up, you WILL have a very bad day…
My favorite flavor is the hex socket head screws. A nearly complete set of wrenches will fit in you pocket. Either fold up or ball end L style.
