Tooth lock washers are specialized fasteners designed to prevent loosening of bolts and screws due to vibration or movement. They feature sharp teeth that grip the surface of the material they are attached to, creating a secure connection. These washers are commonly used in various applications, including automotive and machinery assembly, where reliability is crucial. Made from materials like steel or stainless steel, tooth lock washers come in different sizes and styles to suit specific needs. They are often used in conjunction with other fasteners, such as bolts and nuts, to enhance the overall stability of the assembly.
