Metric DIN 439 is thin hexagonal jam nuts with a thickness of 0.5 x diameter. A hex jam nut is a low-profile type of hex nut, typically about half as thick as a regular hex nut. It is often used as a lock nut, where it is threaded up against a standard nut locking it in place. Also in circumstances where a standard nut is too thick for an application, a hex jam nut can be a very useful alternative. Metric DIN 439 thin hex jam nuts are available un-chamfered (Type A) and chamfered (Type B). These nuts are offered in both right-hand and left-hand threads.
