The OEM 10mm head nuts are junk.

When I go to a hardware store, auto store, construction store, etc, the 10mm nuts are all 17mm in hex size (required socket). I need 16mm or 15mm hex size. Where might I find these size nuts???

 

Doesn't Gary at TVI sell some head nuts for the DS?

 

TVI's are 17mm also, you need to use a Snap-On 17mm 6-point socket (It has a thinner wall).

 

the snap on is the answer
