China Small Washer Manufacturer, Supplier, Factory

In high-performance applications, having the right washers is critical for ensuring long-term reliability and preventing mechanical failure. Small washers may seem simple, but they play an indispensable role in distributing load, preventing loosening, and compensating for thermal expansion. For instance, when you need to maintain tension in a bolted assembly under dynamic loads, Internal Teeth Lock Washers provide excellent resistance to rotation and vibration. Their internal teeth bite into the material, creating a secure lock. Meanwhile, for applications requiring a lighter preload and vibration damping, our Light Type Single Coil Spring Lock Washers offer a cost-effective and reliable solution. When you're dealing with oversized bolt holes or need a larger bearing surface, our Extra Large Washer is engineered to prevent pull-through and reduce surface pressure. And for the highest tension and spring action in demanding environments, the Conical Spring Washer is unparalleled, maintaining clamp force even under significant stress and thermal cycling. Choosing the correct small washer directly impacts the safety, performance, and longevity of your equipment.


The Small Washer is engineered with precision to meet the highest industrial standards. Its compact design belies its significant role in maintaining the integrity of a bolted joint. Below are the detailed specifications and technical data for the standard Small Washer.
