If you're looking to find a way to make the drum tuning process easier, and furthermore, a way to make a deeper tuning of your drums, then the Hendrix Sleeved Washers are the right choice, since they give your tension rods their optimal working conditions.
Since all the metal-to-metal contact will be avoided, your tension rods will now slide more smoothly.
However, the Hendrix Sleeved Washers cannot totally prevent your tension rods from becoming loose unless you use Tight Screws.
If you want to tune your drums rather deeply, these washers will be quite beneficial, since they help the tension rods to stay put in the hoop.
Hendrix Sleeved Washers will be delivered in a package of 20 or 100 pieces, and you can choose between black and white.
