Screw lockings
In the future, locking of screwed connections will gain more and more importance since often not all parameters of influence can be taken into account upon designing.
Characteristics
In total, methods for thread locking which do not require an additional locking element provide higher process liability. This applies especially to chemical thread locks, screws and nuts with locking toothing, direct screw-fittings and, with restrictions, to locknuts according to DIN EN ISO 2320.
Special locking elements which, in addition to their locking function, provide other benefits regarding the joint (e. g. RIPP LOCK® lock washers, NORD-LOCK® washers, HELICOIL® plus screwlock) gain increasing importance. The use of screw locks with form fit (crown nut with split pin, etc.) or screw locks for which the corresponding standards have already been withdrawn (spring washers, tooth lock washers) should be avoided. Up-to-date mechanical systems are often not standardised and / or are subject to patents, legal protection of utility patents, etc.

Withdrawn standards
Until today, the DIN, the German Institute for Standardization (Deutsches Institut für Normung e.V.), has withdrawn the following standards concerning locking elements:
- Spring washers (DIN 127, DIN 128 and DIN 6905)
- Wave spring washers (DIN 137 and DIN 6904)
- Tooth lock washers (DIN 6797)
- Serrated lock washers (DIN 6798 and DIN 6908)
- Safety plates (DIN 93, DIN 432 and DIN 463)
- Safety cups (DIN 526)
- Locknuts (DIN 7967)
- Crown nuts with split pin (DIN 937)
For increased stability, these standards do not provide locking action. Neither are they suitable as setting locks.
