    "BOLT NECK" GUITAR NECK INSERT KIT - "Bolt Neck" is in quotes because they're not bolts, they're screws, but that's another story, not to mention a marketing challenge. The pics on either side of the kit above are of my '01 American Strat that inserts were installed on during a complete refurb in Sept '08. Click either pic for a larger image.

    If you have owned a commercially built bolt neck guitar for any length of time, you may have had problems with one or more of the drilled neck holes stripping. A tight body / neck interface is essential for maximum tone and sustain. A bolt neck guitar can have as good or better sustain than a set or neck through design IF the neck to body interface is done correctly and is tight. I can honestly say that the sustain of a bolt neck guitar set up this way rivals a one piece guitar. I'm one of a few builders who's made a one piece and the only one I know of that has made the comparison.

    Threaded zinc alloy inserts are standard on every bolt neck Onyx Forge custom with excellent results. There have been a number of people who have contacted me after looking at the Onyx Forge site asking if they could buy the hardware to fix a problem neck. This page was put together to help out my fellow players who have a bit of mechanical aptitude. Just about everything is offered here needed to do the job other than a screwdriver and hand-held drill.

    The inserts and screws in the kit provide over 548 lbs. of clamping pressure per screw when tightened to 18 inch - lbs of torque (hand tight - do not overtighten). That translates to roughly 2,195 lbs. of pressure on the 6.56 square inches between the bottom of the neck heel and the neck pocket, or 334 lbs / sq. inch. That pressure essentially transforms your guitar's neck and body into a single piece of wood.

    After installation, you will see improved sustain over the stock configuration. The installation will look the same as the original. Additionally, the neck can be removed and reinstalled repeatedly without fear of stripping the holes. These same inserts are installed in fabrication jigs at the shop and have been used hundreds of times.

    If you're a better guitar player than mechanic, the inserts can be installed here for $65 + actual return shipping (no handling charges) of the neck only. Inserts and machine screws are included in the price. If you ship the entire instrument, I'll install the inserts, check / adjust the setup (relief, action, intonation) and restring the guitar with .010"/.046" American made nickel round wound strings for $115 + actual return shipping.

    "Hey Roy,
    Thanks so much for coming up with this screw and insert system. Saved my favorite Tele. Easy installation and it sounds great. If you every need any recommendations, send 'em my way."

    "Hi Roy,
    About 18 months back I bought an Epiphone Thunderbird off US eBay and had it sent to me here in Australia with the neck and body unbolted. When it arrived I found to my dismay that 2 of the neck screw holes were stripped out. I contacted the vendor who was mortified and gave me 2 choices.....he'd refund my money and pay for shipping back to the USA or pay for it to be repaired here. I was loathe to send it back, especially since the price had been good and it was a present for my wife. I consulted my local luthier who recommended one of your Bolt Neck Insert kits to sort the problem and so I had you send me one and he fitted them for me and set it up. The bass plays brilliantly now and the neck is solid as a rock. Thanks for providing a great product."

    Cheers & God Bless

    "Mr. Bullis,
    I recently purchased the Insert Mod for my Telecaster. The installation was easy and simple. I checked my Telecaster before the mod and I was getting 5 to 6 seconds of string vibration. After the mod I checked it again using new Ernie Ball Nickle 10's. The results astonished me. I was getting 15 to 16 seconds of string vibration. Increased my sustain tremendously. The action all the way up is the same - very close with no fret buzz anywhere. It is like playing a whole new instrument. Had to cut back on my compressor settings because of the sustain. A well thought out product will be modding my other 2 Teles and my Strat. Now my Tele has more sustain than my high dollar PRS."

    Thanks so much for a great product

    "Hi Roy,
    Tim Smallwood here, I'm just putting my guitar thru the paces and even though I have a cheap amp, the guitar sustains like a monster. I'm using an Allparts body and neck, maple neck and board with medium frets, and your bolt kit and I'd say that the sustain has improved probably 25%. I'm shocked how much more lively the guitar sounds. It's just amazing! From now on, any guitar I have that is a bolt on guitar will be using your Neck Bolt Kit."

    "Roy,
    Wanted to give you some feedback:
    I've had some trouble with one of the neck screw threads on my Am Std. Strat because of the neck shim I use, so I looked into threaded neck screw inserts. Found your webpage and thought I couldn't do too much wrong for 25 bucks. So I ordered 2 sets, another one for my Tele. Installation was a breeze with the optional drill insert and the hex wrench even without a drill press (just an electric hand drill) - other than I expected. :-) And it did not just improve neck stability and sustain on the Strat! My Tele ('94 Am Std. / Barden pups / Callaham bridge / RS kit) was already a pretty resonant guitar, but that mod turned it into a sustain monster. Really!! I even had to lower the bridge to get to my former action, so I figure the neck really came closer to the neck pocket. Nice treat for a quarter of a bill!."

    "Roy,
    I wanted to thank you for offering this kit, and the fast shipping. The installation went easier than advertised. I noticed an immediate difference as I was bringing the strings into tune - the whole bass felt like it was coming alive. You are correct about the sustain and tone, and I hadn't even plugged it in yet!
    Thanks again."

    Best regards,

    "Roy,
    I installed your threaded insert kit on a Mexican Fender P-Bass I found on eBay. I am amazed at the difference! The improved sustain is just as you said and when I pick it up, this bass actually feels stiffer. Amazing. This is a project bass and I'm very happy I made your threaded inserts part of my project."
