The external tooth washer is an elastic component featuring outer teeth and an inner hole, which provide locking action between fasteners and the components they secure.
This washer offers several key benefits:
High Reliability: The large interface area of the external tooth washer ensures even load distribution, increasing the fastener's reliability and extending its lifespan.
High Torque Applications: Thanks to its outer tooth design, the washer helps distribute and support axial forces, making it especially effective in high-torque fastening situations.
Vibration Resistance: The washer's elasticity in the axial direction helps prevent loosening due to vibration, keeping fasteners stable and secure.
Noise Reduction: The serrated shape of the washer reduces noise and vibrations during operation, contributing to a quieter, smoother performance.
Wide Applicability: The external tooth washer can be used with various fastener materials and shapes, such as screws, bolts, studs, and nuts.
This external tooth washer is perfect for applications where high torque and reliable fastening are required, such as in automotive, machinery, mining equipment, and rail systems.
