What size is this internal screw for the Macbook Air (A1466)?

Question

I just replaced the battery for my Macbook Air (A1466), but in the process I lost one of the screws (image attached). I initially ordered a standard replacement set from Amazon, but realized it may not contain the specific screw I need.

A lot of the replacement packages seem to be for the external screws. But the one I need is just this specific one. Without it my Macbook's trackpad does not register clicks (based on prior experience).

The website ifixit.com has repair guides for many Apple computers, including the from-mid-2012 A1266 MacBook Air.

One of the entries for this MacBook Air is Replace Trackpad. Step 10 contains this picture, showing the screw in question highlighted. Here's a screenshot:

The instruction text says it is a 1.4mm T5 Torx set screw.
