What is the correct size Allen wrench that should be used for the Epiphone Les Paul Traditional Pro-II Truss Rod Nut? Please don't say 4 mm because 4 mm is too small. Matter of fact, here are the ones I've tried that are "close" to fitting with their results. * 4 mm - the suggested size from what I can find - Slides all the way in, but has about 30 degrees of play. Too much play that I will not risk trying to rotate the truss rod nut since that will strip it out. I can feel the the key slide in to the hex part so I know it is in there. * 4.5 mm - goes in to the center of the nut where it is round (see photo below), but it will NOT go in to where the hex part is. This is too big. * 3 mm - way too small, turns freely when all the way in. * 1/8 Inch (3.175 mm) - way too small * 9/64 inch (3.571875 mm) - way too small too - turns but catches slightly * 5/32 inch (3.96875 mm) - too small too. Catches but still a lot play like the 4 mm * 3/16 inch (4.7625 mm) - way too large * 11/64 inch (4.365625 mm) would be the next size larger than 5/32 but they do not make that size (I've searched for hours). I've also seen this size referred to as 4.4 mm on a few Allen Wrench charts. Some charts "claim" this is a valid Allen wrench size, but I'm guessing it has not been made for decades. The next 1/64th step up from that would be 3/16 which is too large. I've checked the nut to ensure that it was not stripped or rounded, and the edges do look straight and smooth. I've included a photo, which was not that simple to illuminate and it looks kind of grainy due to zoom factor. But I think its clear enough to show the hex edges are clean and not stripped/rounded. Is there a such thing as an odd (non-standard) sized Allen wrench that is actually used to make the adjustments? If so, who sells them and what would be the proper size that they would go by? I've wasted at least a good 6 to 8 plus hours trying to figure this out and at this point I would not be too surprised if this may be an one-off anomaly. Thanks greatly for any and all help that you, or anyone else, can provide, RB
I'm restoring a mid 80's (1984-1985) Kramer Baretta. It's in pretty rough shape. The truss rod nut is stripped on the wrench side (not the threads). Does anyone have a source to get a replacement truss rod nut or have any info on the thread size, etc? Any info appreciated.
