If 13mm is too loose, try a 12mm or an 11mm or a 1/2 or 7/16 or 3/8... Has to be one of them unless your socket is bad.
Tool info please

I am preparing to change the diff oil on my 2017 f350 dually. Dana M300.
Trying to find the socket for the bolts. They are 12 point. 13mm 12 point too lose. Not an E-torx.
Any idea what they are?
Thank you.

Alright. Thanks everyone. I tried 2 sockets and a wrench, just a bit too loose, not willing to see if it would work or round off. I will look for the spline drive sockets, makes sense something is a bit different. I will let you know.

I picked up a nice Husky set at Home D. Standard and metric, what they call universal. They fit all kinds of bolt heads. Hex, 12pt, spline etc. Got the cover loose except for the top and bottom bolt. Then I pulled the bottom bolt and it started draining.
After it drained and I wiped off the cover I noticed that it was stamped in the cover "Drain>". I have never dealt with a diff with a dedicated drain. I was looking forward to pulling the cover and seeing the beefiness within. I guess I am getting too old. I put the bolts back and filled it up. Done.
Thanks to everyone who replied, I learned a bit about the new fastener designs. Another reason to buy more tools. Sigh.
