Fastener washers are essential components in mechanical assemblies, meticulously classified into several distinct categories based on their unique functions and structural designs:
Plain Washer
Standard Flat Washer (DIN 125/ISO 7089): These washers offer reliable performance, providing a smooth bearing surface for fasteners to evenly distribute pressure and prevent damage to your assembly surfaces.
Large Outer Diameter Flat Washer (DIN 9021): Perfect for applications requiring a greater spread of load, these washers prevent stress concentrations and ensure the stability of your connections.
Small Inner Diameter Flat Washer (DIN 9022): Ideal for precision assemblies, they offer tight fits and optimal support where smaller fastening hardware is employed.
Spring Steel Flat Washer (DIN 6796): These provide excellent tension retention and shock resistance, ideal for maintaining assembly integrity under dynamic loads.
Spring Washer
Standard Spring Washer (DIN 127/ISO 7090): Engineered to combat loosening from vibration, these washers spring into action to ensure your assembly stays securely fastened.
Wave Spring Washer (DIN 137): Designed for applications requiring flexibility, these washers offer cushioning and maintain tension where space is limited.
Saddle Spring Washer (DIN 7980): These are perfect for preserving joint integrity in angled or curved assemblies, providing consistent pressure across the connection.
Belleville Spring Washer (DIN 6797): Known for their superior load-bearing capacity, they are used in high-load applications to ensure consistent pressure and prevent loosening.
Lock Washer
Internal Tooth Lock Washer (DIN 6798): Equipped with internal teeth to grip the surface and resist rotation, enhancing the security of your assembly.
External Tooth Lock Washer (DIN 6799): Featuring external teeth, these washers grip the nut or bolt head, preventing any back-off and ensuring a tighter fit.
Double Ear Stop Washer (DIN 93): Specialized for applications needing dual hold points, enhancing the locking mechanism of your fasteners.
Single Ear Stop Washer (DIN 94): A streamlined solution with a single hold point to secure fasteners in place efficiently.
Special Function Washer
Flange Washer (DIN 1440): Designed to distribute loads across a larger area, providing enhanced support and stability to flange connections.
Insulating gaskets (DIN 46395): Essential for electrical insulation, these gaskets ensure safety and reliability in electrical assemblies.
Sealing gaskets (DIN 7603): Created to provide superior sealing capabilities, preventing leaks and maintaining pressure integrity.
Spherical gaskets (DIN 6319): Allow for movement and misalignment compensation, ideal for dynamic and complex assemblies.
Combined gaskets
Flat gasket + spring gasket combination (DIN 6798 J): Offering the best of both worlds, these combinations deliver support and tension retention in one package.
Nylon locking gaskets (DIN 985): Enhanced with nylon inserts for additional locking strength, these are perfect for vibration-prone environments.
Metal-coated gaskets: Providing excellent durability and resistance to environmental factors, these gaskets ensure long-lasting performance.
Non-metal gaskets
Rubber gaskets: Known for their flexibility and sealing properties, they are used extensively in applications requiring airtight seals.
PTFE gaskets: Offering outstanding chemical resistance, these gaskets are perfect for challenging environments and aggressive substances.
Nylon gaskets: Lightweight and durable, nylon gaskets provide excellent resistance to wear and chemicals, ideal for various industrial applications.
Fiber-reinforced gaskets: Designed for enhanced strength and stability, these gaskets offer exceptional performance under high-pressure conditions.
Special gaskets
Stop gaskets for round nuts (DIN 5406): Securely lock round nuts in place, preventing loosening under dynamic conditions.
Lock gaskets for bearings (DIN 5407): Maintain the position of bearings, ensuring smooth operation and extended lifespan.
High-strength structural gaskets (DIN 6916): Engineered for demanding applications, these gaskets provide robust support and load distribution.
These gaskets play pivotal roles in mechanical assemblies, offering critical functionalities like pressure dispersion, anti-loosening, sealing, insulation, and adjustment of clearances. When choosing the right gasket, consider factors like material composition (such as carbon steel, stainless steel, copper, plastics, etc.), hardness grade, and the necessary surface treatments to ensure optimal performance and longevity in your applications.
