What type of screw profile is this?

[JohanPI]

I have a bunch of screws at home that I need to remove. However, they have a profile completely unknown to me (a layman) and all the craftsmen I know, and they are utterly hopeless to remove with any other type of bit or with a grabit. My closest guess from googling is a torq-set profile, but I think the slots look considerably wider. Does anyone know?

It is Grabber that makes those screws for some mysterious reason, "grabber bits" via any search engine and you'll probably find the right one.

They are called Loxbit. https://www.beijerbygg.se/privat/sv/produkter/maskiner-verktyg/maskintillbehor/bits-hylsor/loxbits
