Irp Short shifter set screws
 

I recently purchased an IRP short shifter and one of the two set screws had the head of the screw snapped off. I contacted FT speed to see if I could get it replaced, but I was wondering if it would just be faster and or possible to get the same kind of screw at a hardware store. And just to clarify that I would just need to look for I believe 7mm set screws?

You should be able to get them easily zinc coated or stainless in various sizes. I believe it should be called set screw in english (you could search under hex socket set screw too).
