Description
Internal tooth lock washers are fastening components designed with serrations on the inner circumference. These teeth bite into the surface of the fastener and the material, creating resistance against loosening caused by vibration or torque. Manufactured from high-strength steel with polished or plated finishes, they provide durability and corrosion resistance. Commonly used in mechanical assemblies, electrical housings, and industrial machinery, they comply with ISO/DIN standards for reliability.

Application
Internal tooth lock washers are applied in mechanical assemblies, electrical panels, and industrial machinery where vibration resistance is critical. Their serrated design ensures secure fastening by gripping both the fastener and the surface material, preventing loosening under dynamic loads. They are particularly effective in compact assemblies where external tooth washers may not fit, making them ideal for electronics, precision instruments, and vibration-prone mechanical systems.
