Step 19Spanner "Snake Eyes" Tamper Resistant
[[br]]Also known as Snake Eyes, Pig Nose Screws or Twin Hole. They have two small holes drilled into the head. A special twin pin driver bit is required to both tighten and release the screws. Spanner bits come in sizes: #4, #6, #8, #10.
Be aware there are also Metric Snake Eyes where hole spacing does not match spanner, as well the hole sizes are different.[[br]]

There is also a version of this/version of 'regular slot' as shown in the attached image. I couldn't find it amongst your other images. It can be undone/done up with a snake eyes bit, but not the perfect match.
