Allen key size on brake calipers

[Parrot of Doom]

Gonna change my front discs over the weekend, but I'm missing a couple of allen keys. Does anybody know the size of the bolts on the caliper, and the one on the disc?

2 sizes of spanners are needed for the callipers a 13mm for the outer bolt and a 15mm for the inner. If i remember correctly the allen key is 4 or 5mm
