A 'bi-hex' or 'bi-hexagon' socket is also called a 12 point socket. This is because twelve points are formed where the internal walls of the recesses intersect.The name 'bi-hex' comes from the internal shape of the socket recess being that of two hexagons laid over one another.They are able to fit 6 point fastener heads in twice as many positions as a regular 'hex socket'. This means it is easier to locate the socket onto the fastener in tight spaces. They can also be used to turn square (4 point) and bi-hex (12 point) fastener heads as well, giving them greater versatility.
