2020-07-25 09:03:22

According to the purpose, it can be divided into three categories:

1. Machine screws, set screws and special purpose screws.

2. The machine screw is mainly used for a part that tightens the threaded hole.

3. Screw: It is also a type of fastener composed of two parts: head and screw. The fastening connection with a part with a through hole does not require a nut to fit (this type of connection is called a screw connection, which is also a detachable connection; it can also be matched with a nut for two through holes Fastening connection between parts. Set screws are mainly used to fix the relative position between two parts. Special purpose screws such as eyebolts are used for hoisting parts. The shape is generally a flat hexagonal column.

4. Nut: with internal threaded hole. There are also flat square cylinders or flat cylinders, which are matched with bolts, studs or machine screws to fasten and connect two parts to make them into a whole.

High-strength self-locking copper nut

With high strength, it is a classification of self-locking nuts. The strong side of reliability. It is mainly based on the introduction of European technology as a prerequisite for use in road construction machinery, mining machinery, vibration machinery and equipment, etc. At present, there are few domestic manufacturers of such products.

Nylon self-locking copper nut

It can be used in various mechanical and electrical products at a temperature of -50100°C. Nylon self-locking nuts are a new type of high-vibration and anti-loose fastening parts. The demand for nylon self-locking nuts for aerospace, aviation, tanks, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products and all kinds of machinery has increased sharply , This is because its anti-vibration and anti-loose performance is much higher than other various copper inserts
