The brand new DW set I bought in '01 had the old black plastic covered wing screws on the toms and floor tom. Over time they were harder to turn. DW then made the new style which has a hex bolt coming out of the bracket and a wing nut to tighten which I always felt was a much better design. I was just going to try and replace the hex nut/wing screw with a new bolt/wing nut but the inside of the bracket won't allow for it. I finally bought replacements and am I glad I did! Apparently, the wing crews had gone through the gaskets and made an indentation on the shell. Not happy. Thus, all new brackets. If you have the old style, you may seriously wish to consider replacing them. Pricey- yes, but think how much you spent on your gorgeous, tremendous sounding drums? Totally worth it.
