DIN 936
Metric DIN 936 Low Profile Hex Nuts are similar to a hex jam nut (DIN 439) but with slightly different heights. They are thin hex nuts about half as thick as a regular hex nut. They are often used as lock nuts, where they are threaded up against a standard nut locking it in place or in any circumstance where a standard nut is too thick for an application, a hex jam nut can be a very useful alternative.
