Re: Nylon Plastic Tension Rod Washers...
I have them for the reason that some of the rods won't turn as easy to tune as they do with the nylon or teflon ones. By the same token they can loosen just as easy but since I'm a nice gentle player this isn't a problem. I actually have them on all of my batter heads and also on the snare side heads on the snares.
