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.

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

2nd one as good as the 1st

By

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.

Works fine

By

Verified Buyer


First time building a guitar and first truss rod I've ever even held so I don't know much about the quality compared to other makes. I inserted the rod into the routed channel and after making an access hole in the headstock, I tightened the fitting and could clearly see the rod bowing upward. So I would say that it works as it should.

I have been building since 1976. These are great for any instrument. I especially like them for my banjo necks. Easy to install and they do what they need to do.
