Plain washers provide a smooth bearing surface, distributing load evenly and preventing damage to assemblies. They reduce friction, ensure firm tightening, and maintain joint stability under various operating conditions.

Spring washers prevent loosening caused by vibration or dynamic loads. Their spring-like design maintains tension, ensuring a secure connection and enhancing reliability in mechanical, automotive, and industrial applications.

External tooth washers have outward-pointing teeth offering excellent locking ability. They enhance grip, prevent loosening, and maintain firm connections, making them suitable for high-vibration or heavy-duty fastening applications.

Internal tooth washers feature inward-facing teeth that bite into the surface, providing strong resistance to rotation. They’re ideal for electrical connections and assemblies requiring secure, vibration-resistant fastening.
