Replacing vintage cross-head trussrod nut with hex nut ...

[ikay]

Does anyone know if a Fender American hex trussrod nut (like this - [url="http://www.cdguitars.co.uk/fender-truss-rod-nut---american-series-with-allen-head-009-4943-000----0994943000-379-p.asp"]http://www.cdguitars...43000-379-p.asp[/url]) can be used as a direct replacement for a vintage Fender cross-head nut?

The cross-head nut is 7/8" long, 3/8 diameter and has a 10-32 thread but I can't find equivalent specs for the Fender USA hex nut (only that it uses a 1/8" hex wrench).

Thanks for any input!

I don't know the answer - but all the Fender Hex Nuts truss rod adjusters I've seen are 3/16" AF Allen key fit aren't they ?

Hmm, you may well right but this page here says 1/8" - [url="http://intl.fender.com/en-GB/guitar-bass-parts/string-guides-nuts/truss-rod-nut-18-american-series-guitars/"]http://intl.fender.com/en-GB/guitar-bass-parts/string-guides-nuts/truss-rod-nut-18-american-series-guitars/[/url]

It wouldn't be the first time Fender got it wrong!

The critical specs for me though are the length, diameter and thread size.

I contacted Allparts who sorted me out. Details below in case anyone else is interested.

Fender American hex nut:
Thread 10-32
Length 24mm
Diameter 9.5mm

Essentially the same spec as the cross head nut but 2mm longer so may protrude a bit..
