Spring washer is a type of washer designed to provide a flexible, high-pressure resistance in fastening applications. They are often used in conjunction with fasteners such as screws or bolts to create a more secure connection. The unique design of spring washers allows them to compress and flatten when pressure is applied, providing a vibration-resistant and locking mechanism to prevent loosening over time. They are commonly used in industrial and automotive applications where there is a need for reliable and long-lasting fastening solutions. Overall, spring washers play a crucial role in ensuring the stability and durability of various mechanical assemblies.
