I recently ran into a new one on me, a double ended bolt, metric on one end and usa standard on the other. The larger end is 3/8 x 16 thread, the smaller end is m8 1.25 JIM

what was it from?

maybe somebody stripped the 3/8" on one side and figured a 8mm was the next size to re-tap it to????

I use double ended bolts to hold a head cooling fan on the head of a refrigeration compressor, but they are standard on both ends. Don't know what would be standard on one end and metric on the other.

I see those all the time in the auto industry now days. In fact, I've got a handful of those bolts from Dorman.

I made one of those about 40+ years ago. English/metric bolt. Probably different threads, who remembers such details. It was for his car, a Renault. I believe he had a problem with the air filter. Lost the nut. Metric stuff was not that easy to find back then and the dealer didn't have it in stock. So we got a good old US nut and drove happily off into the sunset.

Not an OEM part but it worked. The two worlds do meet so I can imagine some need for this kind of thing.

Fasttrack got it .That bolt holds transmission to engine, Chevrolet 6.5 diesel pickup truck. That was my first time to see a combination on the same bolt. But I dont often work on small trucks. JIM ps This bolt discovery was about the same time we had long discussion about should we go all metric in the USA?
