Description I’ve been using this Neck Bolt Counterbore since I switched to bolted necks a few years ago. Simple to use and produces a perfectly clean counterbore every time – highly recommended. ~Andrey Lowry, Lowry Guitars I’ve used counterbores for several years to counter sink neck bolts. Some are pretty good, but not great. This one is at least a few steps ahead of the ones I’ve used in the past. The shaft is a few thousandths under a 1/4″, it fits just right in a 1/4″ hole to not wobble and still turn freely. It also leaves the bottom of the hole dead flat. It does exactly what it is supposed to do very well. ~Joe Mendel, Mendel’s Fretted Instruments
