Damaged screwsScrews wear off. It is rare that a screw driver fits exactly. Have a little bit of play and the screw driver will work only at the edges. You'll end up with dented screws. |
Round nutsNuts wear round. Same story, a wrench often does not suit perfectly. In stead of applying force to 6 areas, it will only apply to 6 points. The applied force is the strongest, right on the weakest spot of the nut. Nuts go round. |
An improved design?Could screw driver and screw, wrench and nut have a better grip? Grip on areas, not on points? Even when a bit of wear and tear sets in?Would a better design be possible? |
Yin YangA yin and yang design![]() This works for tightening things, but you'll never un tighten it. |
Two circlesSo, how about a double yin yang![]() Yes, better already. But the outer rim, which potentially can apply most power, hardly contributes. |
Bow tie screwOf course a rounding is easy to let screw and tool fit naturally, like two spoons.
But flat would be even better,
A bow tie screw is born. |
Pizza ScrewSo why just two areas? Why not 3, 4, 5 or 6?![]() Here comes the Pizza screw! |
