2018 Fender jazz truss rod size?

[Rowan_Aitch]

I have a 2018 Fender Modern Player Jazz Bass, strangely it doesn't have the heel adjustment that I've seen on most of them. This has the standard head adjustment. It looks like there is a truss rod that's in a fine state, but I can't find any information about what size allen key I need for it. I have a 1/8" standard Fender size and that's too small, and I have a 4mm size that's too big so I'm guessing it's something like 3.5mm? But I thought I'd check.
If anyone has any info about this strange nut, let me know!

Taking a closer look at the truss rod, it does look a bit stripped. Is it just worth replacing?

“Internet says” 2018 Fender Modern Player Jazz recommended truss rod wrench size is 3/16” I don’t own one. Find a wrench with a good fit remember the ‘help’ the neck along.

3/16" for sure. Someone probably used a metric size that was a touch too small on that bass. That stripped it a bit, but the 3/16" should still be a good tight fit.
