Magma screw size

[puffon]

I've got a Magma clone (don't know the brand) that has allen screws. (grub screws)
I want to swap them for machine screws.
What size thread should I look for?
I tried a 4-40..no-go.
They are probably metric?

The "Atomizers and Cartridges" forum is for discussion of traditional disposable attys. Moved this one to the Rebuildable Atomizers forum

I have an authentic Magma (actually vaping on it now). I don't have any thread gauges handy, but if I remember later on I'll pull a screw out and try to get the measurements. No guarantees it'll be correct for a clone, though it'll at least be a good starting point

In the mean time, maybe somebody else already has this info handy to share

M3, according to this post. I don't own a Magma to verify it though.

No screws on the posts: FastTech Forums

The screws on the authentic are M3, can't get an accurate measurement on thread pitch (cheap calipers) but looks to be around 0.5 (standard "coarse" thread pitch for that diameter screw)

If you're swapping to cap screws, make sure the heads aren't sticking up too far and shorting against your top cap

Thanks for the info!
