Fasteners: The “cornerstone” of mechanical connections and the “link” in industrial systems.

In the modern industrial system, fasteners are fundamental mechanical components used for joining, securing, positioning, or sealing. From small household appliances and furniture used in daily life to high-end equipment such as aerospace systems, construction machinery, and automotive manufacturing, none can do without them. As the “cornerstone” of mechanical connections, although individual fasteners are compact in size and relatively simple in structure, they directly determine the assembly accuracy, connection reliability, and operational stability of equipment—making them a critical link in ensuring both industrial production quality and product performance. From bolts, nuts, and screws to rivets, washers, and pins, fasteners come in a wide variety of types and specifications. Their design, material selection, and application always revolve around the core requirements of adapting to different operating conditions, transmitting loads effectively, and guaranteeing safety.

Four Common Surface Treatment Processes for Fasteners

As the fundamental component for mechanical connections, fasteners often operate in complex environments involving moisture, corrosion, friction, and other challenging conditions. Surface treatment processes not only directly affect the appearance and texture but, more critically, enhance corrosion resistance, improve wear resistance, ensure connection reliability, and extend service life. In industrial production, galvanizing, chrome plating, phosphating, and blackening are four widely used surface treatment techniques, each with its own unique technical characteristics and suitable application scenarios. The rational selection of these processes requires careful consideration of various factors, including operational conditions and cost budgets.

A Comprehensive Analysis of Commonly Used Fastener Materials

As the fundamental component for mechanical connections, the performance of fasteners is closely linked to the materials selected. Under different operating conditions, the requirements for fasteners—such as strength, corrosion resistance, wear resistance, and lightweight design—vary considerably; thus, it is essential to match the appropriate materials accordingly. From general-purpose applications to extreme environments, fastener materials span a wide range of categories, including carbon steel, alloy steel, stainless steel, non-ferrous metals, and specialized functional alloys. Selecting the right material appropriately is crucial for ensuring connection reliability and extending service life. The following sections will provide a detailed breakdown of the characteristics, classifications, and application scenarios of commonly used fastener materials.

Interpretation of the Latest National Standards GB/T 3098.23, 24, and 25 for Fasteners!

The national standard GB/T3098.23-2020, "Mechanical Properties of Fasteners—Bolts, Screws, and Studs M42-M72," was released on March 31, 2020, and came into effect on October 1, 2020. GB/T3098.24-2020, "Mechanical Properties of Fasteners—Stainless Steel and Nickel Alloy Bolts, Screws, Studs, and Nuts for High-Temperature Applications," and GB/T3098.25-2020, "Mechanical Properties of Fasteners—Guidelines for Selecting Stainless Steel and Nickel Alloy Fasteners," were released on November 19, 2020, and came into effect on June 1, 2021. This article provides a brief analysis and introduction to the key design points, material selection, and testing methods outlined in these standards, helping readers better understand and apply them in their work. 1. Introduction Fasteners are a general term for a class of mechanical parts used to securely join two or more components (or structural elements) into a single unit. The primary function of fasteners is to provide secure connections between mechanical parts. They are widely used and characterized by a vast variety of types and specifications, diverse performance and applications, as well as a high degree of standardization and serialization. To ensure that China’s demand for mechanical components and technical standards in areas such as machinery, vehicles, and transportation remain aligned with international practices, enhance the reliability and safety of machinery, marine equipment, wind power generation, construction, mining, and other related equipment, and meet market needs, the National Technical Committee for Standardization of Fasteners has recently revised or developed a series of national standards concerning fastener manufacturing and performance testing. The purpose of these standards is to standardize fastener design, placing great emphasis on the rational selection of materials. In addition to dedicating an entire chapter to “Materials,” many material-selection provisions have also been designated as mandatory requirements. This means that designers must treat proper and optimized material selection as a fundamental skill when carrying out fastener design work. The national standard GB/T3098.23-2020, "Mechanical Properties of Fasteners—Bolts, Screws, and Studs M42-M72," was released on March 31, 2020, and came into effect on October 1, 2020; GB/T3098.24-2020, "Mechanical Properties of Fasteners—Stainless Steel and Nickel Alloy Bolts, Screws, Studs, and Nuts for High-Temperature Applications," was released on November 19, 2020, and came into effect on June 1, 2021; GB/T3098.25-2020, "Mechanical Properties of Fasteners—Guidelines for Selecting Stainless Steel and Nickel Alloy Fasteners," was released on November 19, 2020, and came into effect on June 1, 2021. The purpose of this article is to provide readers with an analysis and introduction to these standards, facilitating their understanding and application in design. Please feel free to offer criticism and corrections if you find any inaccuracies in the text. 2. GB/T3098.23-2020, "Mechanical Properties of Fasteners—Bolts, Screws, and Studs M42–M72" GB/T3098.23-2020, "Mechanical Properties of Fasteners—Bolts, Screws, and Studs M42–M72," specifies the mechanical and physical properties of bolts, screws, and studs in the size range M42–M72 when tested under ambient temperatures ranging from 10℃ to 35℃. Fasteners conforming to the requirements of this standard within the specified temperature range may fail to meet the prescribed mechanical and physical performance criteria when operating outside this temperature range. Fasteners manufactured according to GB/T3098.23 are suitable for use at temperatures ranging from -50℃ to +150℃.
