Hello, K3/10 #685 basic kit arrived 28 April. Arrived in VK on 9 April, spent over 2 weeks in Australian customs. Inventory done, all there but no "4-40" nuts. I'm used to metric sizes, can anyone tell me what "4-40" refers to, so I can see if they are available locally, I don't want to wait another week! Cheers, Chris VK2LCD
