Nuts differ in thread size and pitch, spanner size, height, strength grade and locking method. Metric and inch (UNF, UNC) nuts may look alike but are not interchangeable, and a nut with the wrong thread will damage the bolt thread on the first tightening. The nut is therefore chosen by part number and checked against the bolt thread. Where possible, the nut and bolt are taken from the same strength grade and standard.
