Original Build Journal


DK Percussion is proud to offer custom machined stainless steel tuning gauge bolts, with paint filled letters that will never rub or fall off, and bolt heads that will never break. Special thumb nuts are machined to be as small as possible, allowing for closer spacing of notes on your tuning gauge.

Why the dot? It's meant to act as an accidental letter, such as B-flat or D-sharp. Simply put one of these in between two letters with the dot in the proper location of the indicator arm.


Note: taking full orders on revolving stock and always in production, please check with us if you have a deadline for this product.


Several options exist for making sure your brass thumb nuts do not fall off the tuning bolt, resulting in lost letters!

  • Red Loctite: Put a dab of Red Loctite solution on the end of the thread AFTER installing your bolt.
    (Note: red is permanent, blue is less permanent and just as viable.)
  • Thread crimping: Use a pair of pliers or other tool to "smash" the last few threads on the bottom of your tuning bolt to prevent easy removal of brass thumb nuts.

*Please note: only tuning gauges meant to accept square-neck bolts will be compatible with this design. This includes the "Ludwig Pro" tuning gauge product, many custom timpani, and Yamaha rails.

**Many American Drum timpani use a double rail system with 1/4" spacing, while most use a 3/16". If you require a different size or design, please inquire before ordering for options. We can help update your rail system!

*** To measure your rail spacing without calipers, use an 8-32 (small), 10-24, or 10-32 (larger) sized bolt. If it fits your rail system, these universal indicators will fit. Please confirm prior to ordering.
