I actually thought of grinding a point on my set screws to make them act like spikes....It has to be better than the rounded set screws......I would go to the hardware store and take one stock set screw with you and match the thread size and experiment gringing points on the replacement screws...........
( keep the stock ones as is )and try that..Thas what i am about to do........
