Threaded fittings are everywhere, and there are many types and standards. For inexperienced people, the appearance and performance of threads are almost the same, making it difficult to accurately identify them. Master the necessary thread structure and terminology to effectively communicate with manufacturing partners and obtain the required information. What are the types of threads? How to choose threads correctly? What do the M, G, Tr, and B markings on threads represent? What are the differences between Chinese standard, British standard Wyeth, and American standard threads? Let's take a look together~

Rivet nuts are divided into pull rivet nuts and press rivet nuts. These two tools are not unfamiliar to industrial workers, but many customers do not understand the specific differences between the two and which tool to choose for their own enterprises when consulting. Here, the editor is going to give you some useful information. Today, we will focus on the respective uses and differences of rivet nuts and press rivet nuts.

Although the wheel hub nut is small, it is the "fastening guard" of wheel safety, bearing various impact forces during driving, ensuring that the wheel is tightly connected to the axle. Once loose, hidden dangers such as steering wheel vibration and wheel detachment may cause serious accidents at any time. Installation requires matching specifications, precise torque wrench to 100-150 N · m, daily inspection and rust prevention maintenance, so that this "guardian" can always silently stand guard for your driving safety.

Since late May, the automotive industry has launched a new round of price cuts, and the low price competition in the automotive industry has once again sparked heated discussions. Recently, the China Association of Automobile Manufacturers released the "Initiative on Maintaining Fair Competition Order and Promoting Healthy Development of the Industry" (hereinafter referred to as the "Initiative"), proposing four points: all enterprises must strictly abide by the principle of fair competition and carry out business activities in accordance with laws and regulations; Advantageous enterprises do not monopolize the market, squeeze the living space of other entities, and harm the legitimate rights and interests of other operators; Enterprises shall not dump goods at prices lower than cost, engage in false advertising that induces consumers, disrupt market order, or harm the fundamental interests of the industry and consumers, in addition to lawfully lowering prices for goods; All enterprises should conduct self-examination and rectification in accordance with relevant national laws and regulations.

The export quantity of fasteners in China from January to March 2025 was 1431087 tons, an increase of 215101 tons compared to the same period last year, a year-on-year increase of 17.8%; The export amount was 2738.718 million US dollars, an increase of 198.859 million US dollars compared to the same period last year, a year-on-year increase of 8.2%.

As a leading event in the global fastener industry, the China Shanghai International Fastener Industry Expo 2025 (IFS 2025) was grandly opened on May 22 at the Shanghai World Expo Exhibition and Convention Center. The theme of this exhibition is "Full Industry Chain, Globalization, High Precision", focusing on intelligent manufacturing and green transformation. It has attracted more than 1200 companies from around the world to participate, showcasing the innovative achievements of the fastener industry from raw materials to finished products, and providing a one-stop procurement and technical exchange platform for international buyers.

Nut grades cover various forms, such as ordinary, non-standard, old national standard, new national standard, American standard, British standard, German standard and other different standards. In addition, nuts are classified into Type I, Type II, and Thin types based on their nominal thickness. It should be noted that nuts above level 8 are specifically divided into two types: Type I and Type II.

10B21 is a typical cold heading steel with good plasticity, moderate strength, and significant heat treatment effect. This material is widely used in the manufacture of high-grade fasteners, such as bolts, nuts, etc.

In the mechanical processing industry, the measuring tool that must be prepared for the first contact is undoubtedly the vernier caliper. It plays an indispensable role in daily production activities and is frequently used for accurate measurement of various sizes.

In daily life and industrial applications, we often encounter situations where some sheet metal parts are thin and cannot be assembled and connected through punching and tapping. At this point, the welding nut came in handy. It melts and mixes metals at high temperatures, and then solidifies through cooling, forming strong molecular forces that enable the two separate components to be firmly connected into a whole. Its strength usually exceeds that of the parent material, ensuring the stability of the connection. Welded nuts are widely used in various fields such as automotive seats, sheet metal chassis/cabinets, ships, railways, etc. They are an indispensable part of mechanical parts that transmit motion or power.

Fasteners are known as the "industrial rice" and are a type of mechanical component that plays a role in fastening connections. Although fastener products may not be eye-catching in terms of appearance and size, they play a key role in connecting and fastening various components to form mechanical equipment, and have a significant impact on the overall quality and performance of mechanical equipment. In the automotive industry, fasteners are used for the specific production of various components and parts, as well as the connection and assembly of various subsystems that make up the entire vehicle, and play an important role in vehicle manufacturing.
