Question About Torx Fasteners On Aveo5

[2010AveoLT]

Sorry if this is a Noob question but here goes. I see the bolts that mount the thermostat on my Wife's 2010 Aveo5 LT are Torx but are they SAE or Metric? I assumed Torx was it's own standard, it wasn't until I looked at getting a female socket set for working on her car that I saw mention of two types. Any help is appreciated.

It’s usually part of the metric system; because they are in 1mm increments.
