I have an application where a 1" dia. shaft is hard to R-62 and a part is attached with two opposing 3/8" cup-point set screws. The part has a cam follower on it and rotating the part on the shaft then locking it with the set screws is a positioning adjustment. There is about 75 pounds of force on the part. I hate this set-up! I just don't trust it not to slip but I can't think of a better way of locking the part on the shaft yet be able to adjust it easily.
