Fastener Standards and Norms

Fastener Standards and Norms

Fasteners are critical components used in various fields, from industrial manufacturing to construction, automotive, and aerospace industries. Bolts, nuts, washers, screws, pins, and rivets are among the essential parts that ensure the durability and safety of a structure. Adhering to specific norms and standards during the production and use of these fasteners is of great importance.

Fastener Norms

Fastener standards regulate various factors, from dimensions and material types to thread structure and mechanical strength. Different standards such as DIN, ISO, IST, HSS, ART, and M ensure production in compliance with national and international regulations. These standards not only guarantee the safe and long-lasting use of fasteners in various industries but also enhance compatibility between components.

For example, DIN standards, established by the German Institute for Standardization, are widely used across Europe and globally. ISO standards, developed by the International Organization for Standardization, provide a common framework for manufacturing processes in different countries. IST, ART, and HSS standards are specialized regulations designed for specific industries and production requirements.

Selecting the right standard for fasteners not only enhances assembly safety but also directly impacts long-term durability. Fasteners made from specialized materials, such as stainless steel bolts or high-strength screws, offer superior resistance to wear, corrosion, and high loads.

Below, you will find a comprehensive list of standards used for different fasteners. This list will help you choose the most suitable fasteners for your projects. For more information about our fasteners, contact us.

Bolt

Bolts are one of the most commonly used fasteners designed to securely hold two or more parts together. They are typically used with a nut to create a strong connection. Available in various head types, thread patterns, and materials, bolts are widely preferred in industries such as construction, automotive, machinery, and aerospace. Manufactured according to DIN, ISO, and other international standards, bolts are designed to meet specific load-bearing and corrosion resistance requirements. For more information, check out our article What is a Bolt?.

Nut

Nuts are threaded fasteners used together with a bolt or stud to secure components in place. Available in various types such as hex nuts, flanged nuts, nylon-insert lock nuts, and cap nuts, nuts can be used with supporting elements like washers to enhance connection security. Typically made from materials such as steel, stainless steel, brass, and plastic, nuts are widely used in applications ranging from mechanical systems to electrical devices.

Washer

Washers are thin, disk-shaped components that expand the contact surface of fasteners, ensuring that bolts and nuts distribute clamping force evenly. They also help prevent wear and damage at connection points, extending the lifespan of the fastening system. Available in various types such as flat, spring, serrated, and wide washers, washers play a crucial role in applications where mechanical loads need to be distributed evenly.

Screw

Screws are fasteners used to secure components by either self-tapping or being inserted into pre-threaded holes. Available in various types such as self-drilling screws, Phillips head screws, and chipboard screws, screws are specifically designed for use with different materials like wood, metal, plastic, and concrete. Widely utilized in industrial manufacturing, the furniture industry, and electrical-electronic applications, screws provide durable and practical fastening solutions. To learn more about different types of screws, check out our article: Types of Screws.

Pin

Pins are cylindrical fasteners used to hold two or more parts together or to restrict movement in a specific direction. Available in various types such as cylindrical pins, cotter pins, and retaining pins, pins are often preferred for detachable connections. Commonly used in mechanical systems, machinery, and the automotive industry, pins ensure proper alignment and secure fastening of components.

Rivet

Rivet is a fastener used to create a permanent connection by being compressed between the joined materials, forming a durable structure. Commonly used in applications requiring the joining of metal surfaces, rivets stand out with their high strength and vibration-resistant properties. Available in various types such as pop rivets, multigrip rivets, and hemlock rivets, rivets are widely preferred in the aerospace, automotive, shipbuilding, and furniture industries.
