ASME/ANSI B 18.3 Alloy Steel Cup-Point Set Screws

Hexagon socket flat-end set screws are also called machine screws and set screws. They refer to hexagon sockets with flat ends at the head and tail.

High strength, corrosion resistance, and fatigue resistance

The main characteristics of alloy steel hexagon socket flat-end set bolts include high strength, corrosion resistance, and fatigue resistance. These characteristics enable the bolts to maintain stable working performance under various harsh working conditions, ensuring the reliability and safety of the connection.

Detailed characteristics of alloy steel hexagon socket flat-end set bolts

High strength: Alloy steel hexagon socket flat end set bolts usually use high-strength alloy steel as raw materials, such as SCM435, SCM440, etc., and are carefully selected and strictly tested for quality to ensure that the physical properties and chemical composition of the raw materials are stable. Through advanced heat treatment processes and precision machining technology, the bolts' tensile and yield strength have reached extremely high levels, with tensile strength reaching about 1200MPa to 1220MPa and yield strength not less than 1080MPa.

Corrosion resistance: The surface of the bolts is usually specially treated, such as galvanizing and blackening, to improve their corrosion resistance and aesthetics. These treatment processes can effectively prevent the bolts from rusting and corroding in a humid and corrosive environment, extending their service life. For applications that require higher corrosion resistance, more advanced anti-corrosion treatment processes such as nickel plating and chrome plating can also be used.

Fatigue resistance: The bolts have undergone precision processing and heat treatment processes and are highly fatigue-resistant. In the fatigue test, the cyclic load of the bolts in actual work is simulated to evaluate their fatigue resistance and service life. The test results show that this bolt grade can maintain stable performance under long-term cyclic loads and is not prone to fatigue fracture.

Application scenarios of alloy steel hexagon socket flat-end set bolts

Alloy steel hexagon socket flat-end set bolts are widely used in various mechanical and industrial equipment that require high strength and corrosion resistance. Due to its high strength and corrosion resistance, it is particularly suitable for equipment working in harsh environments, such as the chemical industry, marine engineering, and other fields.

In summary, alloy steel hexagon socket flat point set bolts perform well in various harsh working conditions due to their high strength, corrosion resistance, and fatigue resistance, making them ideal for many industrial applications.
