1. Main types and features
DIN444 bolts are divided into three types: A, B and C, of which A and B are more common in the market. The main feature of these bolts is that they use a movable joint connection, have a large angle adjustment capability, and can adapt to different installation requirements. At the same time, they also have good seismic resistance, fatigue resistance and corrosion resistance.

2. Material and surface treatment
Material: DIN444 bolts are generally made of carbon steel, stainless steel, etc. Carbon steel bolts have excellent machinability and a wide range of strength performance combinations, and the cost is relatively low; stainless steel bolts have better corrosion resistance and high temperature resistance.
Surface treatment: In order to improve the corrosion resistance and aesthetics of the bolts, they are usually surface treated. Common surface treatment methods include galvanizing, hot-dip galvanizing, spraying, etc. These treatment methods can effectively protect the bolts from environmental corrosion and extend their service life.
3. Size and specifications
The size standard of DIN444 bolts is based on the metric system, including bolt diameter, thread length, thread type, etc. Specifically, its nominal diameter range is usually M5 to M30, and the conventional length can be 100mm, but it can also be customized according to customer requirements. In addition, the thread specifications and pitch of the bolts are also designed and produced according to specific needs.

IV. Application fields
DIN444 bolts are widely used in occasions where parts need to be adjusted or tightened, such as machinery and equipment, vehicles, building structures, etc. Especially in occasions or tooling that need to be frequently disassembled and connected, such as safety instruments (mine detonators, filter-type self-rescuers, gas detection instruments, dust masks, mining raincoats, etc.), DIN444 bolts play an irreplaceable role.

V. Production process and quality control
Production process: The production process of bolts includes material selection, spheroidizing (softening) annealing, shelling and descaling, cold drawing, cold forging, thread processing, heat treatment and other links. Each link requires strict control of process parameters and quality standards to ensure the performance and quality of the final product.
Quality control: Manufacturers usually have complete testing equipment, such as hardness testers, spectrometers, salt spray testers, etc., which are used to test and evaluate the hardness, dimensional tolerance, anti-corrosion and anti-rust properties of bolts. Through strict quality control, it can be ensured that the bolts have reliable connection performance during use.
In summary, DIN444 bolts are a fastener product with a wide range of applications and excellent performance. Its reasonable design, excellent material, perfect surface treatment, and strict production process and quality control make it widely used and recognized in various industrial fields.
