Default Differential Fill Plug question??????

Quick question: Today I changed my differential Fluid on my 93. I noticed the fill plug was tight before the plug is flush against the differential housing. Is this normal? I tried to use a 10mm to remove the plug but that was too big to I had to used a pair of pliers to remove the plug. I was just wondering if may car has the correct plug or not? The plug seems to be plastic also.
Anyone have this same issue?

Thanks for your help!!!!

I always just use a pipe wrench. I've tried to fit a hex wrench in there and end up back to the pipe wrench.

I used a plummer's pipe wrench to losen mine up and then switched to channel locks to remove it. No problems; worked great
