Neck bolt inserts

[The Burpster]

Has anyone taken the standard neck ‘bolts’ which are really woodscrews and  replaced them with proper bolts and inserts like Montys or Nek tite?

 

I like proper engineering and whilst I know the woodscrews have been used for decades but these products claim to increase sustain and tone. 
 

i like the idea I could torque them identically. 

Thoughts?

Dunno about increase sustain or tone... but i likes the engineering approach.

 

Although the internal threaded part looks quite short... but the height of a nut i spose.

 

I'm sure there are such things available from Spaldings (who i use for Stainless Dog Point Grub Screws for Bridge Saddles) or other Fastner shops.

If it is a bass that you have to regularly adjust the truss rod (assume neck heel Fender type), then yes. I have neck inserts on a bass where that was the driver. Fairly easy job for a competent DIYer. As @PaulThePlug said, I didn’t notice any difference in sustain or tone though.

I did it on a Harley Benton tele I owned. I felt like it made it more resonant. No scientific measurements were made though!

 

Easy enough to do with a hand drill. Just make sure you go deep enough for the threaded insert and then use a countersink bit to just bring the edge down a little before putting the insert in.

are the inserts glued or pressed in, or both?

They were screwed in on mine.

Depends. The ones I used were screwed in. For extra security I put epoxy on the threads and in the cavity as well before final tightening.

Most of my builds have been neck-through but, when I was asked to build a bolt-on neck or do a major repair, I have always used screwed-in inserts and machine-screws.  Whether it adds anything the human ear can pick up is debateable but a tight joint will certainly suffer less string vibration losses than a loose one - and you don't have to worry about stripping threads with proper inserts.

There's quite some information here about threaded inserts, you just have to do some searching. 

 

I like them, easy and functional. My travel bass has a Status neck with inserts. I detach the neck before going to the plane.

 

Soundwise it doesn't matter, wood bolts or inserts, but inserts are reliable, and enable multiple removals without any issues.
