Spring washers have a small footprint and are valued in small machines where a coil spring would be unsuitable. Spring washers can also deflect in a linear, progressive, or regressive means and these devices show a symmetrical deflection around the washer's axis. Spring washers can be stacked to create spring sets or series where deflection and load capacity can vary without materially affecting the forces involved.

In the requirements analysis phase, the specification can help specify the customer's vague requirements, and identify the conflicting, ambiguous, and unstated requirements. Hardware fastener industry even more so, the specifications of the products size are different, Jiaxing Goshen hardware's offe
