| Post subject: | Damaged truss rod nut |
Got an Epiphone Texan (adjustable bridge) on the bench, truss rod is adjusted by what seems to be a 5mm allen headed barrel nut. Seems to be a bit rounded off (not by me) and stiff. I thought SM sold tapered allen keys for this kind of problem, but don't seem available. Any suggestions? |

They do have tapered profile hex keys in the form of screwdrivers. A very worthwhile addition to any tech's toolbox. Saved my butt countless times. But they are only available as hex keys. Pierre |

Have you tried SAE wrenches? My shop notes say that both 1/8 and 9/64 are used on some t/r's. |

Older (60s) Texans would have used the same truss rods as Gibson’s, with nut adjusters. Recent, Asian production likely uses the ubiquitous 4mm hex truss rods. A pic will help a lot. Pierre |

My experience with newer epi truss rods hasn't been good. The design is weak....using the reverse function of the 2 way rod unassisted usually results in breakage. The nuts are soft and strip quite easily. So again, always bend the neck by hand and take up slack with the rod when adjusting these. Once stripped or the retainer broken.... It's replacement time. |

It's a 60's Texan, its a 5mm barrel nut on the truss rod, 6mm thread on single action truss rod and it's out. Owner just turned up on my doorstep and when I showed him he gave me the courage to give it a tweak out (with lubrication) |

P.S. Found the SM wrenches I had searched for, but I was using the wrong search terms. https://www.stewmac.com/Luthier_Tools/Tools_by_Job/Tools_for_Truss_Rods/Gripper_Truss_Rod_Wrenches.html |

Already ordered. Hen's teeth apparently, but got one similar but slightly shorter, will pack out with a couple of washers all being well otherwise. |
