Yep. Never a good idea not to have a positive locking mechanism. If it ever came loose without the flat to prevent rotation the bore in the pulley would get chewed up and loose. I have been recommending that everyone get their pulleys modded to the larger setscrew also because a lot of guys are rounding off the hex head in the stock ones. The stock hex wrench size is 1.5mm (.059") and I'm changing the setscrews to #8-32 UNC which have a 5/64" or .078" (2mm) hex.
Serious only a 1.5 on the pulley's ? oh my.
