It’s usually cost. They have tooling for components that have probably been around decades. The cost of retooling just to change the fastener sizes may not be economically viable. Eventually these legacy components will be phased out and it will be 100% metric.
Comment on everything actually important is already metric
ThatWeirdGuy1001@lemmy.world 4 weeks agoMt last car was a 2012 ford fiesta. The lug nuts are 19mm. The caliper bolts were 10mm and the slide bolts were 3/8.
The car before that was a 2001 cavalier. Not only did it have metric and standard bolts but the slide bolts were fuckin Allen heads.
Like literally why?

Probably because they were made by American car manufacturers and couldn’t make a logical or consistent design decision if their lives depended on it.

Like I’m not even an engineer and I’m just screaming about the dumbest decisions made by people who make more in a week than I make in a year 😭

The last one I ran into is that the Windshield Washer Fluid Reservoir in a Chevy Bolt is about 1/4 cup smaller than a standard 1 gallon jug of fluid. You could have expanded the tube by less than 1/8 of an inch and fit that remaining 1/4 cup of fluid in there.

Yeah, but the difference is that they made it so you need an extra socket or an alan wrench. I think you’d have made dumb decisions that were a little bit more deadly.
