1G 1G frt sub frame bolt fine thread

[troppo loungo]

Looking for bolt fine thread size of large pointy bolts that hold the front fore aft cross members to the front cross member. It appears that 1/2 inch nf 20 works however I feel they should be metric. I need to chase the threads.

They are 12 x 1.25MM

They are 12 x 1.25MM

This is correct.

Oddly enough, I just ran into this at work. A 1/2-20 nut (thread pitch of 0.050 inches) will thread onto a M12x1.25 fastener (thread pitch of 0.049 inches), but it is really loose due to the difference in diameters (0.500 inches nominal versus 0.472 inches nominal). Just a fun fact.
