    Who designed this so called Ground Screw and Why?

    What exactly is this kind of screw supposed to be good for?
    The top edges of the HEX are rolled so as to create something that approaches no hex at all. Ridiculous.
    The hex measures about 304" or 7.7mm take your pick. A 5/16" nut driver does not work well and will slip. Exactly what kind of ultra specialized tool is one to use other than Phillips screwdriver? The metal is also if inferior " soft " stock. This type of screw was once better, but has gone way down hill. Whatever the logic for it, its an Engineering blunder. The real surface area of the HEX is almost nonexistent and then exactly what kind of tool is specified? Why is this being done?

    Probably originally designed to be installed by a machine.

        Agreed. Bad design. But I guess I'm just jaded and used to things getting cheaper and useful details ignored. I use a Phillips tip and it'll just have to be good enough, even though the hex would have been much more useful, handy, and secure, had they bothered to make it usable.

          Don't your complaints deal with 1 manufacturer's attempt at a grounding screw? Maybe the ones with the attached green lead are better. Maybe...

            Dennis, I do not find them to work anywhere " near " fine. MAC702 is on the same page. Not so long ago they did not have that silly chamfer on the crown. You could throw one into a Mag nutdriver and go through a ring terminal and land it easily and securely. Whatever this downgrade is, its a colossal joke and I find them fully unacceptable, useless, and a time waster.
            In short they suck.

              Quit buying them then. Find others that are better.

                Well, 5/16" = 7.9375 mm
                You measure at 7.7 mm
                You need a 39/128" socket.

                What's wrong with using a P2 bit?
                Maybe you need a flat-blade for greater torque.
                Perhaps someone makes an S2 grounding screw.

                  Perhaps the Happy Sun Fortune Cookie and Ground Screw Company that makes them also has a tool for them.

                    What brand screw is that? I just went to the basement and the screws we have work fine. I don't really notice much rounding and they work fine with a nut driver. They are metallics JGSH 22 31lVAxm44YL.jpg

                      The ones pictured there work even better with a #2 Robertson (square).

                        How are the ones pictured in my post different from the others. The photo is not very good in the op's post

                          I like square drive, too.

                            Hex works fine in the ones I posted. I think I prefer the hex

                              I think a lot of guys carry the square in their tool pouch because they fit most all electrical devices - receptacles, switches, breakers, etc. They may not have the nut driver close at hand.
