What is the actual size of a Y1 Tri Wing screwdriver?


Just interested to know if Y1 = 3mm.

The OP of this question replied that the Y1 Tri wing screwdriver that is recommended to use in the Nintendo Switch battery replacement guide was too big and the correct size was actually a 1.5mm Tri wing screwdriver.

Is this a typo in the guide perhaps?

(I've linked to the author of the guide @technoanarchist in a comment to my answer for the question, but no response as yet)

Searching online I've found a 3mm Tri wing Y1 screwdriver (not the only listing stating this) which makes it a bit confusing as to the actual size. Y1 or 3mm or does it mean the same thing?

Is this a good question?

The Tri-point screws used by Nintendo don’t really go by mm sizes, they’re a special conical shape, so measuring 1.5 or 3.0 mm doesn’t really apply. If the Y1 is too big, then it’s likely that the screws are a Y0 size. They could even be a Y00, but I doubt that they would be as small as a Y000.

The inscribed size of a Y1 point is ~1.6 mm, a Y0 is ~1.25 mm

Hi @brett

Thanks for that.

Seems as though there is no standard definitions for Y series tri-wing screwdrivers then.

Found lots of links to a Y 0.6mm Tri wing screwdriver, Some differentiate it by saying 0.6mm tri-wing screwdriver with a Y tip

So to clarify it for me, there is the Y series tri wing drivers of indeterminate size except by designation Y1, Y0, Y00 etc and the metric sized tri wing drivers with a Y tip.

Have I got it about right?
