Triple Square / XZN driver dimensions

I don’t know why this is so hard to find on the ’net, I couldn’t find any specifications anywhere.

The dimentions below are measured off a set of male drivers made by Neiko. I don’t know how true-to-spec. these are, and I wouldn’t put it past my hurry to get the measurements not quite right.

Therefore, use this as a guide only.

* “C” is hard to measure, especially in the small sizes

If you find the actual specs published somewhere, I’d love to have a link to them.

Here is a primer from Metalnerd®.  They make good stuff.
