Four common types of self-locking nuts

In order to avoid accidents, the demand for hardware nuts is further increased, and self-locking nuts are developed. Self-locking nuts can relax and resist vibration. There are four major series that are common in daily life. Nuts are common parts of machinery and equipment, but due to the vibration of machinery and equipment during work, the nut is prone to loosening, which can cause damage to the machinery and equipment in severe cases. First of all, we must understand the four common types of self-locking nuts.

Four common series of self-locking nuts:

1. High-strength self-locking nuts

High-strength self-locking nuts are a classification of self-locking nuts, which have high strength and strong reliability. It is mainly used in road construction machinery, mining machinery, vibration machinery and equipment, etc.

2. Nylon self-locking nuts

Nylon self-locking nut is a new type of high-vibration and anti-loosening fastening parts that can be used in various mechanical and electrical products at a temperature of -50~100℃. At present, it is mainly used in aerospace, aviation, tanks, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products and various machinery.

3. Swimming self-locking nuts (Guide: Note 4 points for stainless steel screws to prevent rust)

A common floating self-locking nut is a double-lug sealing floating self-locking nut, which is mainly composed of four parts: a sealing cover, a self-locking nut, a pressure ring, and a sealing ring. It has a compact structure and a reliable seal. It is suitable for products whose working pressure is no more than 2atm and the working medium is gasoline, kerosene, water or air and the working temperature is 50~100℃. But it has certain difficulties in manufacturing process and air tightness test.

4. Spring self-locking nut

The spring clamp self-locking nut consists of an S-type spring clamp and a self-locking nut. It is easy to use and has very good reliability. Combining the nut with the locking principle, developed different self-locking nuts to prevent the nut from loosening during use. With the development of the scientific and technological age, the use requirements are changing in different generations, and my country's self-locking nut technology is also continuously improving, which is expected to be in line with the international level.
