Metric anything is for foreign cars. Foreign car mechanics at dealerships are the highest paid mechanics because working on foreign cars sucks. Metric fasteners are not the only one of their stupid ideas. It’s a criminal shame that their stupid ideas have overcome American automotive manufacturing. Cars used to be rebuildable, now they are just disposable appliances. They used to have style and class, now they look like colored jellybeans. And 95 % of the mechanics out there don’t know how to fix anything, they just know how to replace parts.

Most any car made today “ domestic” or foreign..all use metric fasteners. Been that way for a while.
And many “ domestic “ cars have more foreign parts in them than many foreign car manufacturers use.
Check out percent of domestic parts used in a variety of popular selling cars today. You will be surprised at what you find.
