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.

Love these!!

By

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

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.

I have not installed these yet, but have used them before, and they have worked perfectly. I have no reason to believe these will be any different

This is the second one I've used because it's easy to install and I know it will work. I had to tweak the neck on the Banjo I completed in June after everything settled in it had a little back bow and this rod took it out with no problem. The Banjo is White Oak so if it works here it should work on others.
