Self-locking nuts

Self-locking nut or self-locking - a type of fastening that has a simple but very reliable design. Its main function is to protect the threaded connection from untwisting. Self-locking nut - a kind of self-locking, the principle of which is based on the method of frictional braking. High-quality self-locking nut will provide an extremely strong connection.

Design and principle of operation of self-locking nuts

Self-locking nut consists of:
• hexagon nuts;
• inner contrasting (locking) ring.

The system of self-locking nut is complex only at first glance. In fact, the principle of its operation is quite simple. The inner nylon ring tightly wraps around the thread of the respective connection, strengthening the mounting location and preventing it from untwisting. The inner ring is usually a nylon liner. But the inner snap ring can also be made of other materials, such as plastic. The design of the self-locking nut allows not to use additional locking consumables in the form of rings or engravers.

Hexagon self-locking nut can be made of stainless steel strength class 6 to 12, brass or aluminum. Materials for the manufacture of self-locking nuts have good performance properties, which allows you to use them even in aggressive conditions. The use of self-locking nut is possible in almost any field (it is used to secure various elements, both in everyday life and in various industries).

The sizes of self-locking nutsThere are two main standards governing the dimensional and design features of the self-locking nut:

• DIN 982 (high self-locking hex nut);
• DIN 985 (low self-locking nut).

Diameter of both high and low nuts - from M3 to M48. Such a wide diameter range allows you to buy self-locking nuts to secure structures of completely different sizes.
