What is an External Tooth Lock Washer?
An External Tooth Lock Washer is a circular fastener with sharp, outward-facing teeth along its outer edge. These teeth grip the surface of the material, creating resistance to rotation and loosening. External tooth lock washers are commonly used in applications where a secure connection is essential under dynamic loads or vibrations.
What are external tooth lock washers used for?
Internal locking washers are able to bite into fasteners. They can specifically bite into the head of a screw or bolt, thereby holding the fastener in place. External locking washers are better suited for biting into surfaces. They are typically larger than internal locking washers.
Uses of External Tooth Lock Washer
- Prevents loosening of bolts, nuts, and screws caused by vibrations.
- Provides additional locking force in high-torque applications.
- Ideal for use in machinery, automotive assemblies, and industrial equipment.
- Enhances grip and reduces the risk of fastener back-off.
- Suitable for use with large or flat surfaces to distribute the load evenly.
