Quad Alphanumeric Display - Red 0.54" Digits w/ I2C Backpack

What is the diameter of the mounting holes for the Quad Alphanumeric Display - Red 0.54" Digits w/ I2C Backpack? (https://www.adafruit.com/product/1911)

The picture on the download page (https://learn.adafruit.com/adafruit-led ... /downloads) does not show it and I have no idea what "Drill=2" in the EagleCAD footprint means... (Clearance for an M2 (.079) metric screw?)

The holes are drilled to 0.100", but then get plated (strangely enough, that costs less).

M2 and M2.5 bolts should fit through the existing hole, and you can tap them to take a 4-40 thread.
