Hello,
I own sapphire M5's and i m interested in adding Herbies threaded stud gliders on these M5. Does anyone know what is the thread size that i should choose from? Or is there any way to measure the correct size properly?

Thanks!

M6 is the size. I use them on my Sapphires M3s at one time. You can also call Spatial to check.

I did call them, the new owners do not have an answer. so relying on our forum members

I use the ones that don't attach.

Go to a hardware store- get an m6 screw and a 1/4” one too. One of those will be correct- my M3 Turbos use 1/4”, though the newer models probably went metric. It shouldn’t cost more than 2 bucks, and you’ll know for sure.
