Metric 12 fine thread
What is the pitch of a metric thread?
For example, an M12x1.75 (coarse) thread has a 1.75mm pitch, while an M12x1.50 (fine) thread has a 1.50mm pitch. Both DIN and ISO standards for metric threads ignore the pitch callout on coarse threads. For example, a thread diameter defined as "M12" indicates a coarse pitch (M12-1.75).

Why are metric thread specifications different?
Metric thread specifications are different because the thread pitch is defined by the distance between each thread in mm instead of threads per inch. For example, an M12x1.75 (coarse) thread has a 1.75mm pitch, while an M12x1.50 (fine) thread has a 1.50mm pitch.
What is the tolerance of metric screw threads?
The illustration below show the tolerance of the metric screw threads. 5g6g: For DIN 912 or ISO 4762 Property class 12.9 socket head cap screws (class 8.8 and stainless steel socket head cap screws have 6g tolerance). ANSI B18.3.1M uses 4g6g for all socket products regardless of strength class and material.
