"Hex Keys" is a new fancy name fashionable in department stores and corner shops and 7/11 Service Stations (aka "Gas Station")... but real men who have a "shed" would never buy tools at such establishments: but rather will drive the "ute" down the "the hardware store" and get the proper stuff which "Tradies" use.
... the other "it" is known as a "Socket Head Cap Screw" - it would be understood that the Head would be an "Allen" head, unless otherwise stated. (the same applies for socket "grub" screws - its taken as granted those would be "Allen" unless otherwise stated)
There are several fancy socket head cap screws now available, recently making it necessary for me to spend an horrible amount of money to buy a 100 bit set for my driver, just to get a set of three of those funny star shaped ones.
I think collecting tools costs more than cameras.
That's it today for me. Hope it made some of you smile.
