4mm Allen Nut Hot Rod Truss Rod

After trying out a few brands of other truss rods, I've used this type on all of my guitars. Excellent stuff!

Sorry but I find the nut anchorage to the bar not enough resistant.
Others truss double action rod are more resistant in that zone

Well made, easy install and perfect fit using the Stew Mac truss rod router bit. I have used 6 now with very good results.

I have built 8 electrics with these and I find them convenient to install since they use just a flat bottom channel.
I had one shear at the adjuster once, which made me livid, but I was able to save the neck and replace the truss rod without removing the fretboard. Always lubricate the threads and test it before installing. Proceed with caution while adjusting any truss rod.
On Fender style necks, with the adjuster oriented just under the fret board, the tightening/loosening direction is opposite to conventional so watch out for that!!
Finally, I'm glad there is now metric adjuster sizes!!

It works realy well no rattle in the neck.Also theres no need for a large truss rod cover

Just received the 4mm allen nut Hot Rod, and butchered a nice piece of wood trying to install it with adjustment at head stock end. CAN'T BE DONE ON A FENDER GUITAR but StewMac doesn't mention that anywhere. It can only be installed as a heel end adjuster) The 7/16 slot depth puts the adjuster too low into the head stock to allow access. If you want a heel end adjuster, buy the Fender style model, and don't mess around with an oddball 4mm adjustment.

I love these hot rod truss rods. They are incredibly easy to install and use. The dual action has come in handy on a kit guitar I built. I use them on my electrics and acoustics.

Installs easily and precisely and the fact that works in both directions allows you to straighten the fretboard wile leveling the frets. Perfect

I have always used these truss rods for my guitars. They work perfectly every time!

I have purchased many of these truss rods and they work great. I use some woods harder then rock maple and have never had a problem with installation or use. Their service is top notch and I always get my order in two days. The trade secrets articles have given me the confidence and knowledge to do many guitar projects right the first time.
