4mm Allen Nut Hot Rod Truss Rod

About This Item

A smaller 4mm (5/32") Allen nut for most instruments. Smooth two-way action corrects upbow and backbow, giving complete control over the neck.

Easy to install. The Hot Rod® fits in a straight channel. For proper operation, this truss rod must be installed so that the active rod (the rod with the adjustment nut) is below the passive rod. A wooden filler stick is not required.

Smooth 2-way action with superior strength for stubborn necks.
Our Hot Rod neck adjustment system features twin rods in threaded brass collars. The stainless steel active rod turns for smooth neck alignment, with 2-way action to correct upbow and backbow.

The Hot Rod requires an access cavity for the adjustment nut, and a straight 7/32"-wide x 7/16"-deep slot (measured from the bottom of the fretboard) for installation.

Another example of great StewMac service

I ordered this truss rod for an upcoming build. When it arrived, I noticed both rods were loose but I figured I could fix this.

Without any action necessary on my part, StewMac sent a replacement truss rod for free. I have never heard of anything like it.

For years I was using a different type of adjustable truss rod from StewMac. About a year or so ago I tried a Hot Rod and was very pleased. The adjustment is smoother than the other type. I've been using them ever since. Terry - TNM Guitars

Great truss rod, could use some improvement

By

Verified Buyer


I bought this as a replacement for an identical truss rod that failed in a bass that was brought to me for repair. The rod had frozen up, perhaps due to corrosion, and the adjusting nut had sheared off the rod. If it had been a replaceable nut, instead of one that was welded to the rod, the repair would have been much simpler. As it was, I had to steam off the fret board and replace the entire rod assembly. That said, when it works as designed, it is a great product.

Looks well built, but so far I have not had to adjust the truss rod in the guitars built from StewMac kits.
