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.

A time saver

By

Verified Buyer


I've made my own truss rods in the past. This is a time saver and a much smoother method of neck adjustment.

great for guitars

By

Verified Buyer


These are great truss rods but have a tight fit on Stew/Mac necks. However I made a fence from a spruce sound hole cut out and used it with my Stew/Mac sound hole and rosette jig and after several passes to the proper depth on both sides of the slot it fit perfect. Adjustments are as true as can be.

My go-to truss rod...

By

Verified Buyer


I have put this Hot Rod in 12 guitars now and in terms of price and performance, I don't think these can be beat. The low profile and low weight give great flexibility in terms of neck design and shape. Great design all around.

Hot Rod

By

Verified Buyer


These truss rods, time and again, perform extremely well -- and I have used a LOT of them. Quality construction, and the fact that they are light weight and two way make them the perfect choice for any instrument. Because I also make bouzoukis, with necks longer than a guitar, I need a rod that I can rely on, and this is it.

Another example of great StewMac service

By

Verified Buyer


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.
