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.

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.

I've used these quite a few times and never had a problem! Trust me, once a Hot Rod is installed in a neck you can hang a Buick off the headstock and the neck WILL stay where you put it!! I've yet to run into a truss rod problem that this didn't solve. I've used it for weak necks, crappy truss rods, no truss rod, you name it, this works!! Haven't tried to Low Profile version, but have no fears that when I need one it will do the trick. Why? Because StewMac recommends and sells it. If all companies operated and had customer service like StewMac, the entire world would be a better place!!

Fits my truss rod slot perfectly. Smooth action. Much nicer than some of the other brands I have used. Thank you

Perfect fit!

I've installed five of these and all five perform flawlessly, which is imperative when you've got so many hours in a neck build. And the double action gives you peace of mind that no matter what you can correct a bow.
