Chuck,
Your link isn't working. I think if you want to get real technical they maybe considered "Low Socket Head Cap" as they are flatter then the normal Socket Head Cap screws. If you look at this picture:
there are two socket head caps. These screws are more like DIN6912 vs DIN912. Not sure if it looks like a cheese wheel but I guess it could. TIA!
Measure the head. If it's around .138 tall, it's a standard Torx drive socket head cap screw. If it's shorter than that, it's a Torx drive low head cap screw.
