Upgrading Spikes on Target Wall Shelf

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........

I have been replacing the points on my equipment with Star Sound Audio Points gradually. So far have them under my REL subs, replacing the stock feet on my Scoutmaster, unthreaded ones under my stand mount speakers and under my components. I have some target stands that I am going to try soon. In every case there was a noticeable improvement.

haven't upgraded (changed) spikes, but i've changed the shelf out, with great results. using a neuance board, which i think are no longer made, very time consuming to make, i'm told. i've heard of some people on the cheap changing the stock boards out with birch ply with good results.
