Purchased a new B.O.R bottom bracket today. It came with its own installation tool, which has this socket on the back of it.

Never seen it before anybody know what its called / what I need to look for.
Many thanks

Allen key, with the corners pre-rounded for bodgers 😉

Yes, that'll be for an Allen key...

Allen key. It's had the corners of the hex drilled to make it easier to machine.
