FAQ
How do I tell standard from fine pitch?
Measure the distance between threads with a metric thread gauge. An M12 standard pitch thread is 1.75mm; fine pitch M12 is 1.5mm or 1.25mm. The nut must match the bolt pitch.
Do serrated nuts need a washer?
No. A washer under the serrations would stop them from locking.
