Spring washers, also known as disc springs, are a type of fastener commonly used in mechanical assemblies to provide flexibility and absorb shock or vibration. These washers are designed to maintain tension and prevent loosening of the bolt or nut they are paired with, making them a crucial component in ensuring the stability and integrity of the assembly. Their unique shape allows them to exert a spring force when compressed, creating a secure and reliable connection. Available in a variety of sizes and materials, spring washers are a versatile solution for a wide range of applications in industries such as automotive, aerospace, and manufacturing. With their ability to enhance the performance and longevity of mechanical systems, spring washers are an indispensable tool for engineers and designers seeking to optimize the functionality and durability of their creations.
