Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Usually yes. Most standard strap buttons use a similar screw and shaft size, so the washer seats the same way. Oversized or recessed buttons are the exception.
No. They protect the finish and add a little friction, but they are not strap locks. If your strap slips off, get locking buttons or rubber strap blocks.
Six, using two per guitar. Most players use one at each button, under the strap.
Between the body and the strap, so the washer takes the contact instead of the finish.
