5, where "M12" denotes the major diameter of the thread and "1. 5" is the pitch.
Essential Tools For Measuring Lug Nuts Accurately
This measurement in millimeters corresponds to the pitch indicated in the nut's size designation. Confirming this visually ensures you purchase the correct replacement hardware.
If you do not have a gauge, you can use a digital caliper to measure the distance from the peak of one thread to the peak of the adjacent thread. Conical seat nuts, the most common type, feature a tapered hole that matches a corresponding cone on the wheel hub.
How to Use a Thread Gauge and Digital Caliper for Lug Nuts
Incorrect pitch leads to cross-threading, which can instantly damage the stud and create a dangerous loose wheel. Lug nuts are universally specified using metric measurements, such as M12x1.
