neb: These hex head screwdrivers: It seems to be a requirement that IP-rated electrical/electronic device enclosures come with hex-head SS screws and bolts for no known reason, which are a huge pain to deal with because you need Allen keys that you change your grip on every half turn which requires having at least three hands, one to hold the equipment up/down/against a wall/whatever and two to fumble with the Allen key. These screwdrivers turn hex-head bolts and screws into standard one-handed-operation items like Phillips-head screws, and if necessary you can give them the final tighten once the equipment is already bolted into place with an Allen key and one hand.

Because phillips and similar are a turd of a fastener and need to go and die. I would rather torx than hex because the screws hold onto the bit better. If I have to deal with hex head I would want ball ended screw drivers so they can go in at an angle.
