External tooth lock washers are versatile components used across a wide range of industries—from automotive and aerospace to electronics and heavy machinery. Their primary role is to prevent loosening of fasteners due to vibration, torque, or thermal cycling. They achieve this through outward-facing teeth that bite into the mating surfaces, forming a secure grip.
They’re especially useful in applications where space is limited, but performance is non-negotiable. Whether it’s securing a motherboard screw or bolting down industrial equipment, their design ensures consistent torque retention and longer service intervals. For engineers and procurement specialists looking for a single solution across multiple use cases, external tooth lock washers check every box.
