300 Utility Water Pump Set Screw

I need a new set screw for the water pump collar on my 300 Utility. The one that I took out had a pointed tip which seems odd to me. It would seem it would have initially had a blunt tip to fit into the keyway on pump. Is my best bet to go to Tractor Supply and pick up something similar?
 
The blunt is normal. However,someone has replaced the original with what you have now. Wont hurt a thing.The original had a slot for a screwdriver,was long enough for a thin locknut. the one you have now is an Allen head?
 
A "half dog" (blunt) tip slotted set screw is original. However any 1/4-20 x 1" set screw works. I've even used a 1/4-20 socket head cap screw in a pinch.
