About Spring Lock Washers

Spring lock washers, also known as split lock washers, are mechanical components designed to prevent nuts and bolts from loosening due to vibration or torque. These washers feature a helical split, which allows them to exert a spring-like force when compressed, creating additional friction between the fastener and the surface. This friction helps maintain a secure connection, even in high-vibration environments.

At Teshi Fasteners, we manufacture spring lock washers from high-quality materials, ensuring they deliver consistent performance and durability. Our spring lock washers are available in materials such as carbon steel, stainless steel, and alloy steel, with various coatings to enhance corrosion resistance and longevity.

Key Features of Spring Lock Washers
