You need to be careful, many Japanese cartridge screws are M2.6.
The van den hul xgw I use has threaded holes M2.5
Selection of screws to attach cartridge to headshell
I bought a kit from Amazon with a mix of screws. $10,00 Trying to get a great connection head shell to cartridge. Should I put something between head shell - cartridge that connects them better. My sense the screws in the kit are not good enough. Any recommendations? Cartridge is van den Hul. The cartridge is threaded. Should I find the right screw that has the right thread and avoid having a nut? Any place where I should look? Thank you.
