What size studs/bolts on clutch fan?

[Mr Brewster]

i took my 92 runner to get serviced the other day, and the mech. said i had to tighten my clutch fan, so i did, but i descovered that there was an entire bolt missing, so it took the whole thing off, and i ordered a new fan online(cuz the other one broke in the processe), and one of the studs/bolts broke. so i need to know what size the studs/bolts are so i can get a new one. i used a 10mm wrench if that helps. the stud screws into the clutch fan then the fan blade goes over it, then a bolt tightens on over all of it. so is it a stud or a bot?

they are studs.. im not sure on the size but they are standard toyota fan studs used in just about all toyota fans. i pulled my fan off conpletly and installed a thermo fan.. shes heaps quiter on the road and i can set my cut in temp and it only cost me AUS$150
