'96 Hub removal, strange fasteners

Need to replace the hub, but both the axle nut and the three hub to steering knuckle bolts have a serrated end which nothing like any socket I've ever seen. Looks almost like the end of a giant torques bit. The steering knuckle bolt ends have about 14 ridges. How do you get on these little suckers?

Have you tried a 12 pt socket? I believe they are 13mm on D30. Try here for a walk through.

Many thanks brainy, you nailed it.
