I'm not familiar with that crank, but it may be that you are looking at an extractor ring that threads in after the crank bolt is secured. At least some of these self extractor rings have small holes and require a spanner wrench to remove. But if this is your situation, you don't need to worry about it because to remove the cranks you leave the extractor ring in place as you unscrew the hex bolt, this is what allows you to remove the cranks without a crank puller. Once the cranks are off, there's still no need to remove the extractor, you can re-install the cranks with the extractor still in place-
