Metric bolt question

We don't measure or weigh stuff or gauge speed in metrics in the U.S. .. What fasteners are used is up to whatever the manufacturer wants to use.
Older vehicles have more standard fasteners on them, but the newer ones are pretty much all metric fasteners now a days. I still do find that some standard sockets fit better on some bolts while metric fits better on others.
Good luck!

Reminds me of my '00 Dakota that takes a rare 17mm hex to remove the drain plug on the tranny (NVG3500). Why not a regular bolt??

All of these fasteners have more points of engagement than a Phillips or external hex. The Torx design has the tool engage in rounded portion instead of the pointed tips. This allows torque to be transferred without risk of stripping out the head better. It's a better design even if we have to buy a few new tools.

Yeah, I still have the special tool that I had to buy from the Mac Tool Truck to remove the head bolts from my 1971 Pinto 2.0L Ford of Germany engine. It had internal splines of some sort (not torx)I had never seen before. That OHC engine had a defect in that it developed an oil leak at the head/block mating surface. The Felpro head gasket I bought came with instructions to torque the head bolts about 15 to 20 ft. lbs. more than the Ford spec to keep the gasket from failing.
