This is just exactly what you expect. Nothing fancy. I just needed a longer one to make an adjustment on the guitar and this one did the trick.

It doesn’t fit into the sound hole. I tried forcing a little then stop to not to hurt the guitar. To me it was useless. Been produced for something else probably.

I put this work right when it arrived on a Martin-style guitar with the truss rod inside the soundhole. It's so far in that you would need to use the short end of a normal Allen key for leverage, and on an old beater like this it's a lot of force. This totally solves the problem and should last many years. You can get a much finer feel as you turn because you are only exerting a little force at a time (I think it's easier to control 2 vs 4 lbs instead of 15 vs 17, for example). So it just feels safer and better. I had no idea they made equilateral allen keys like this. If you work on your acoustic guitar this will be handy. PS - always always always add a drop of light lubricant to the allen key every couple years or if it is giving any pushback at all!

Inexpensive and very good quality Truss, also perfect in size. Rod wrench for correcting intonation!
