5/16 AF is 7.9mm, so would be very close to 8mm for sure.
I know when I changed mine I had to rummage around to find the right socket - but it was 4 years ago and I can't quite remember the details. 99% sure I had to use my imperial/AF set though.
I don't think the PF nuts are Whitworth, but if so it would be a 3/8" AF.

what casues the ticking with pf discs is the nuts and bolts heat and cool this casues the metal to expand and contract while the wheel spin if these are loose then will make a ticking
i have tightend mine up now no ticking but been told that i may have to re do it 4 times in the first 1k miles on the rotor

have been a major UK distributor for PFC for years and never come across that requirement at all, they should be torqued on initial install and then they are a "fit & forget"
i would suggest they need checked and the reason for the noise identified as its not normal

The noise happens on mine with light braking,continues when coasting and sounds a bit like when I used to put a lollipop stick in my bicycle spokes as a young lad to sound cool doesn't sound so cool on the Scooby haha
I will take my pads out and give them and the calipers a good clean again,smear some copper grease on the pad edges and see if I can get rid of the annoying tick tick tick.
