When it comes to fasteners, DIN 394 is a popular standard that is trusted by engineers and manufacturers around the world. These fasteners are known for their high-quality materials and reliable performance, making them ideal for a wide range of applications.
In this guide, we’ll take a closer look at fastener DIN 394 and everything you need to know about this standard. From its history and design to its applications and benefits, we’ll cover it all. So let’s dive in!
What is Fastener DIN 394?
DIN 394 is a German standard for hexagon head bolts with a flange. These fasteners are commonly used in machinery, equipment, and construction applications where high-strength and corrosion resistance are essential. The standard specifies the dimensions, materials, and mechanical properties of these bolts.
History of Fastener DIN 394
DIN 394 was first introduced in 1936 and has since been revised several times. The current version of the standard is DIN EN ISO 4162, which was published in 2012.
Design of Fastener DIN 394
Fastener DIN 394 features a hexagonal head with a flange that provides a larger bearing surface and prevents the bolt from sinking into the material. The bolt also has a shank that is threaded for engagement with a mating nut or threaded hole. The standard specifies the dimensions of the head, shank, and thread, as well as the material and mechanical properties of the bolt.
Materials Used in Fastener DIN 394
Fastener DIN 394 is available in a variety of materials, including steel, stainless steel, and titanium. The choice of material depends on the application and the environment in which the bolt will be used. For example, stainless steel is often used in corrosive environments, while titanium is ideal for high-temperature applications.
Mechanical Properties of Fastener DIN 394
Fastener DIN 394 is designed to provide high-strength and reliable performance. The standard specifies the mechanical properties of the bolt, including its tensile strength, yield strength, and elongation. These properties ensure that the bolt can withstand the stresses and loads that it will be subjected to in its application.
Applications of Fastener DIN 394
Fastener DIN 394 is used in a wide range of applications, including machinery, equipment, and construction. These bolts are ideal for applications that require high-strength and corrosion resistance, such as in the automotive, aerospace, and marine industries. They are also commonly used in structural applications, such as in bridges and buildings.
Benefits of Fastener DIN 394
Fastener DIN 394 offers several benefits over other types of fasteners. First, its hexagonal head with a flange provides a larger bearing surface, which reduces the risk of the bolt sinking into the material. This increases the clamping force and ensures a secure connection.
Second, the standard specifies the dimensions, materials, and mechanical properties of the bolt, which ensures consistent quality and performance. This makes it easier for engineers and manufacturers to select the right bolt for their application and reduces the risk of failure.
Finally, fastener DIN 394 is available in a wide range of materials, which allows engineers and manufacturers to choose the right bolt for their application and environment. This ensures that the bolt will perform reliably and last for a long time.
Conclusion
Fastener DIN 394 is a high-quality standard for hexagon head bolts with a flange. These fasteners are widely used in machinery, equipment, and construction applications where high-strength and corrosion resistance are essential. They offer several benefits over other types of fasteners, including a larger bearing surface, consistent quality and performance, and a wide range of materials.
