Best Truss Rod/Hex Key Tools — FAQ

Can you adjust a truss rod with an Allen key?

Most modern guitars have an Allen bolt that is adjusted with, you guessed it, an Allen wrench or key. When you're adjusting the truss rod, make sure the Allen key is seated properly in the truss rod nut; push it all the way in. If you don't, the nut can be damaged when you try to turn the wrench.

Likewise, what tool do you need to adjust truss rod?

The tool needed for this adjustment is a 1/4 'nut driver' wrench available at any hardware store such as Ace. They used to be small enough to fit, but recently many driver brands seem a little too large and some grinding on the outside diameter may be necessary.

Meanwhile, do all truss rods use the same tool?

Different guitar builders use different size truss rods and you need the specific type wrench and exact size for your guitar. Some truss rods are adjusted with a socket wrench while others use an allen wrench and others may use different type wrenches.

In addition, can a truss rod tool work for every guitar?

Not all guitars have truss rods. This is because not all guitars have a need for a truss rod. Most classical guitars don't use truss rods. This is because the tension created by the nylon strings isn't as strong as the tension created from steel guitar strings.

On the other hand, which way do you turn truss rod to lower action?

To compensate for undesirable curvature in the neck you can adjust your neck up or down. Decrease Relief Tightening the truss rod by turning it clockwise influences the neck to curve upward toward the strings (convex).

Similarly, how do you know if you need a truss rod adjustment?

Two primary signs tell you that your truss rod needs adjusting:

  1. There's a noticeable change in the action; the height of the strings over the frets has become either too high or too low.
  2. Some strings buzz on the frets between the nut and the fifth fret.

Nonetheless, how do you use a guitar Allen key?

With the headstock facing away from you, turning the Allen key clockwise will tighten the truss rod, reducing the neck relief (straightening the neck) and conversely turning the Alley key anticlockwise will loosen the truss rod, increasing the neck relief (allowing more neck bow).

Thus, what causes fret buzz?

Changes in humidity and temperature can commonly cause fret buzz. Fret buzz is a buzzing noise that occurs when the string vibrates against one or more of the frets. Sometimes you can experience fret buzz in the open position, and other times it could be specific strings and/or frets.

Eventually, does tightening truss rod lower action?

A truss rod is NOT for adjusting action.Despite the fact there is information around the web telling readers to adjust their truss rod to raise or lower action, a truss rod is not for adjusting action.

Thereof, what size hex is a truss rod?

Up until June of 2018, our truss rods have required a 5mm wrench (Allen wrench, Allen key, hex wrench, or hex key). Any guitar purchased in June 2018 or sooner now require a 4mm allen wrench. Some older guitars used 5/32 wrench. Any hardware store should also carry a wrench of the correct size.

And, how long does it take for truss rod to adjust?

Give the Neck 1-2 Days to Fully Settle After a Truss Rod Adjustment. It can take a day or two for the neck to fully settle into an adjustment.

Moreover, is a truss rod an Allen key?

Not every truss rod uses an Allen key for adjustment - for example, Taylor guitars need a special Phillips head screwdriver and a 1/4" nut driver. But if your guitar has the original truss rod, some Squiers take a 3/16" Allen key. That's about 4.75mm, so metric keys aren't going to work. Others use metric.
