Drilled spanner screwdriver, I need one.

[DeliveryGuy]

I need a screwdriver for these screws.

They are face plate screws for the exterior key switch to apartment parking garage doors. (I service these, not just trying to break in lol)

All I can find are "Spanner" screwdrivers, which are more like an interrupted slot, rather than two round holes. The name of the screw in question is a DRILLED spanner screw.

I took a caliper measurement of the screw holes in these screws I've seen. They are about .200" outside-to-outside, not center to center. Here's my Avator-level cgi rendering of the screw in question.

Any help will be much appreciated.

You might try one of the Harbor Freight security bit sets.
I am pretty sure one of them has that bit in it.

Are those called snake eye/ pig nose screws?

 

[DeliveryGuy]

Yes. Although, I thought that "pig nose" referred to the regular spanner screws.

No the correct name is Spanner Head Screw

Snake eye screws are used to secure hall and car fixtures on elevators as well. I carry one of these:

I don't necessarily like the size of the screwdriver, but it has all the bits that I might need for oddball fasteners.
