Hex wrench sizes for Variax JTV 89F


Recommended Posts

Can anyone confirm these are the correct Hex wrench sizes for the JVT 89f.  Specifically, for the neck and bridge string locks.  I lost the original and bought a set that had a 7/64" wrench based on a post I found in the Support forums, but it seems like a 7/64 is just a smidge tiny and has enough play in it that after using it a few time it's starting slip while tightening it...and I'm not over tightening it.

 

These were the sizes posted:

 

1 - 4mm hex, for truss rod adjust JTV-89F (relief)
1 - 5/64" hex, for individual piezo level intonation adjust (intonation)
1 - 7/64" hex, for Locking nut and bridge string locks
1 - 3/32" hex, common generic tool in most guitar tool kits

I just pulled out a caliper and checked mine:

4mm - for truss rod

2.5mm - for piezo location on bridge intonation adjust

3mm - for locking nuts and bridge string locks

Then I grabbed a multi-wrench unit and double checked.

 

3mm is 0.118", which wil give a tighter fit than 7/64 at 0.109".

Sorry, I didn't see Psarkissian's response before i posted mine.

 

The 2.5mm for intonation (my wrenches read a bit under at 2.45mm) works out to be 0.096", which is pretty much the same as 3/32" (0.094").
