I have a S1K also and went out and looked at mine. Yes it does have a allen head screw there for the adjustment. I had never tried to remove it though. The biggest scope I ever had on it was the 40 mil BSA. I think I tried a high mount to eleaviate any obstruction of the pin. Now ai have a small 30 mil BSA scope on it.
Maybe a couple of grade 8 nuts. Use two and jam the two together on the screw. Then once you have locked the two nuts together on the screw, use a wrench to unscrew and a new allen wrench at the same time. Of course turn the bottom nut counter clock wise at same time as you turn the allen wrench.
I don't know if this will help but be careful not to strip the threads on the screw.
