Heavy-duty wrenches for hex truss rod nuts, including the familiar 5/16" Gibson® rod. 10-3/4" (27.31cm) overall length keeps your knuckles safely away from the peghead.

Our veteran guitar technicians developed these high quality steel truss rod wrenches for the repair shop. The length, comfortable rubberized handles, durability, and variety of sizes let you perform truss rod adjustments efficiently.

Not all truss rod cavities are the same width. Make sure the wrench will fit your cavity by comparing the outer diameter of the wrench barrel to your guitar.

Wrench Outer diameter
#6101 For 1/4" nut 0.390" (9.91mm)
#6102 For 9/32" nut 0.410" (10.41mm)
#6103 For 5/16" nut 0.440" (11.18mm)

These tools are available in our money-saving Truss Rod Wrench Set.

Ever round out a truss rod nut, and can't turn it?

By Peter Coplin from Princeton, New Jersey

I recently rounded out a truss rod nut on a CC Gibson Les Paul, trying to take out some relief. I was using the typical Gibson wrench, you know the one that you turn a right angles to the axis of torque (looks like a little pipe). Well , I messed up the nut and stopped dead in my tracks before it was a lost cause. I got on the site and ordered this wrench for the gibson nut thinking the power of a better wrench might get me out of this jam. And lo and behold, - with ease I backed out the rounded nut, and put on a fresh new nut, and was able to use the power of this wrench to adjust the neck perfectly. Everyone should have one, instead of that other thing.

This is a professional's tool absolutely perfect for the gibson humming pro I haveàalthough the darn thing is still buzzing around 8 9 10th frets or soàacross all the strings no matter which way I turnà.i adjust it every day now for over a week..i hope i'm not permanently damaging my git.This tool will turn the rod very easy so take it slow.

Perfect tool for my vintage project!

I was working on an old Speed Demon hollowbody and couldn't find any other tool that would work to adjust the truss rod. A regular socket wouldn't fit in the tight space and forget using a wrench in there. I slid it on the old 5/16" hex head and it fit like a glove. A few turns later and the neck is straight again for the first time in decades.

excellent tool

They just take up a lot of space when not in use but work very well

This is a professional quality tool. I have a cheap one and its a Dollar Store quality compared to the StewMac one.

5/16" truss rod wrench

By bluzfish from Edmonton, Canada
(Customer's Reviews) Saturday, December 29, 2012

I needed a truss rod wrench for a couple of Gibson guitars I purchased and although I actually wanted a T type, I am happy now that I purchased this one. It has a sure grip but with a good mechanic's feel, I feel more in control of the tension applied than if there was more torque available. Also, the socket walls are thin enough to get a good purchase on the nut in a tight space. The perfect tool for the job!

Good Tool

The tool worked well. The long shaft takes the handle out of the way of the headstock so there's little to no chance that you'll damage the guitar or scrape your knuckles. Made the adjustment very easy.

Very comfortable ergonomic handle. If you need more torque call someone who knows what they are doing:)!!!
