External tooth lock washers are essential components designed to prevent fasteners, such as bolts and nuts, from loosening due to vibrations or dynamic loads. Their distinguishing feature is the series of sharp, outward-facing teeth that grip the surface material and create additional friction, ensuring a more secure hold. These washers are widely used in applications where maintaining tight, reliable fastenings is critical, such as in automotive, aerospace, electrical equipment, and heavy machinery.
The primary function of an external tooth lock washer is to provide added resistance against rotational forces. The teeth bite into the surfaces they are in contact with, helping to lock the fastener in place. This design is particularly effective when used with soft materials like aluminum or plastic, as it prevents the fastener from slipping or loosening under stress. In metal-to-metal applications, external tooth lock washers ensure that the fastener stays in place despite vibrations or temperature fluctuations.
External tooth lock washers come in various materials, such as stainless steel, zinc-coated steel, and brass. Stainless steel washers are often preferred for applications requiring high corrosion resistance, while zinc-coated washers offer enhanced durability at a lower cost.
