Cool, thanks. I'm looking to use the holes on the back of the motor, I believe there are 3 or 4. The thread info would be sufficient, since I'll measure the rest for my mounts. I just don't have anything remotely close to get an idea of what the threads are.
As long as you get the right thread and length (which is the original question) that works, of course.
The holes are bigger than m10 - this much I know. I used some m10 bolts for my adapter plate, and there wasn't even any thread engagement with those, and there was plenty if room. I suspect he meant 12 or 14As long as you get the right thread and length (which is the original question) that works, of course.
Bolts are not as simple as they may seem at first... are these for shear or tension, do they have a flanged or plain head, etc.
M14 is a huge bolt, probably the largest in the vehicle; it would have a shear strength of at least 40,000 N (four tons). Do you mean an actual 14 mm thread, or just a 14 mm head hex? Threaded fasteners are specified by the thread size, not the hex size; in metric, the thread size in millimetres is prefixed by "M". For example, the wheel studs and nuts for a car (such as the Leaf) are M12 (and commonly M14 for pickup trucks).
- a bolt with an M14 thread would typically have a 19 mm head hex in a car, even larger for non-automotive applications
- a bolt with an M12 thread would typically have a 17 mm head hex in a car, a 19 mm for wheel nuts, and a 21 mm hex for Toyota shank-style wheel nuts (bolts for brake calipers and major suspension components)
- a bolt with an M10 thread would typically have a 14 mm head hex (all but the largest mechanical connections)
- a bolt with an M8 thread would typically have a 12 mm head hex (substantial housing bolts, large electrical connections)
- a bolt with an M6 thread would typically have a 10 mm head hex (common small housing and bracket bolts, and electrical connections)
I'm guessing that these are M10 (with 14 mm hex) and M8 (with 12 mm hex) bolts.
A small note: the grade would presumably be "10.9", not just "10". Metric bolts follow ISO grades which have two values separated by a dot, not just one number like SAE bolt grades (in which Grade 8 is the usual "high grade" choice). OEM bolts may not show a grade on the head at all, because they are a specific part to meet a specific spec, rather than being marked for general-purpose use.
I'm only concerned with the threads, I'll figure the rest out on my own.Holes greater than 10 mm in diameter means M12 or M14 bolts... sounds like you've got it.The holes are bigger than m10 - this much I know.

Yeah, great idea. I'm thinking of the same at the moment...Holes greater than 10 mm in diameter means M12 or M14 bolts... sounds like you've got it.
I just keep a couple bolts of each common thread in a toolbox drawer, and use those to check for size as required.

I don't think anyone will have SAE grade 8 in a metric bolt.
I think "grade 10" for property class 10.9 is confusing, and if you followed the same shortcut and called a property class 8.8 bolt (the next common grade down) just "grade 8" that would be really bad, because the material characteristics of an ISO property class 8.8 fastener are not like an SAE grade 8 fastener (it's about SAE grade 5).
Just to confirm, the bolts into the back of the motor are m12x1.5? I measure the holes as about 150mm deep. My local hardware store doesn't carry that size, so I just want to be sure before ordering. Thanks!
The front ones are m10, the ones on the back appear to be m12. I wasn't sure would would have been m14!
Lol, ok good. There's an Ace down the street and I kept the receipt. Thanks!
No worries! I'm looking forward to you getting that Samurai rolling. I made a bracket... we will have to see how it holds up.
