NGM8054UC/01 Bosch igniter removal

I have a Bosch cook-top in which one burner fails to light. I would like to change out the igniter but cannot remove it. I understand I need to remove the bolt in the center of the burner however, it is so thin that it does not really clear the bevels on the edge of a socket set, and the socket slips off. I tried using PB Blaster to loosen it up but without result. Is there a trick or tool that I need to remove this or am I going about this the wrong way?
See picture below.
Thanks.
