Look in those cardboard holders in small shelves for odd bolts, washers, etc. that most hardware stores have.   I bought some black oxide "cap bolts" in 1/4 x 20 for the larger Emersons and the smaller size below for some of the smaller fans but there is yet a smaller bolt I think to fit some other 8 or 9" Emersons.   Be sure the bolt you buy has sufficient length of threads to reach the rotor.   Nobody could tell me if the bolts I bought were grade 8 or hardened but I'm pretty sure they are hard.  I bought two for each size fan to place in both of the upper gearbox holes.
