DIN 127 spring washers, also known as Grover washers, are spring-type fasteners that help prevent bolt-and-nut connections from loosening. They are used to improve the stability of bolted connections in structures subject to vibration and mechanical movement. They are known internationally as Spring Washer, Split Lock Washer and Grover Washer.

The elastic shape of the spring washer creates additional tension when compressed and helps reduce the chance of a bolt-and-nut connection loosening by itself. Washer size is selected to match the bolt diameter: M6, M8, M10, M12, M16, M20, M24 and other sizes.

• Spring-shaped, split construction
• Used in bolt-and-nut connections
• Helps prevent loosening due to vibration
• Available in various nominal sizes
• Carbon steel and other material options
• Zinc-plated and other surface finishes, compliant with DIN 127

DIN 127 Grover washers are used in steel structures, construction and assembly work, machine building, industrial equipment, mechanical installations, automotive and equipment, engineering systems and vibrating machinery. The washer material and surface finish should be selected to suit the operating environment and the bolt material.
