Screw Rusting
Got this tank a few weeks ago and another 2 elsewhere.This is an great MTL tank,but screws are rusting,i have loads of spare screws but cant believe an Ulton clone would use so crap screws.i think the screw size is 2.5mm in diameter.Also as others have said top cap o'ring and deck o'ring need changed to smaller ones

me too.
The water of the ultrasonic washer became brown and turbid. The cause was a screw.
Waiting for spare screws to arrive.

Not good at all.

You can measure the threaded part on the ones you have, e.g. with a caliper (length and width).

Then go here and choose from the listed SS 304 screws: SKU 3989300

Use the model dropdown menu to choose the size and head(s) you want.

In this post I picked up that the post screw size should be 2.5mm in width:

That would limit the choice to SS 304 M2.5 screws with heads:
SKU 3976804 and downwards in the dropdown menu.

Mine rusted as well...kinda upsetting...there was a constant strange taste and reddish color on top of srews.. i got it only now that this is Rust...dat is kinda dumb btw..excelent work on the atomizer ruined by 2cents rusting screws .
Good thing that screws are easily replacable.

Ofc the other spare screws got rusted quickly as well.


On the original site is reported that screws are indeed "M2.5 x 4mm large pan head philips"

have you tried the post screws you mentioned (on the ulton clone)?
I think these should be the right ones (the other has the head "flared"..if it's the right term) SKU 3989201

I'm wondering if i can buy it from a local hardware store ..dont wanna w8 a couple of screws from china u.u

p.s. i dont have a caliper

If you look at the GrimGreen's review of the genuine one, his screws are also rusted.
I'm not sure I'm allowed links...
