Manufactured in accordance with DIN 936 standard lock nuts, Designed with a low-profile hexagonal structure, it provides connections in confined spaces. It is typically used with a second nut to prevent bolts or screws from loosening. Thanks to its compact design, it is widely used in machinery and equipment, particularly in applications where mounting space is limited.

En belirgin fark yüksekliktir. Standart bir somunun yüksekliği çapın yaklaşık %80’i kadarken, DIN 936 ince somunun yüksekliği çapın yaklaşık %50’si ile %60′ı It is in between. That is, it is much thinner than a standard screw.
The most common purpose is to prevent the main nut from loosening. After the standard nut is tightened, a DIN 936 nut is attached behind it and tightened in the opposite direction. This process creates tension between the threads of the two nuts, preventing them from loosening due to vibration.
Fiber-reinforced nuts are single-use and the nylon inside may melt at high temperatures. Metal-to-metal counter-locking with DIN 936, however, is resistant to high temperatures and can be removed and reinstalled multiple times. For this reason, DIN 936 is preferred over fiber in engine and exhaust connections.
