High Strength Spring Washers from China Suppliers - Reliable Factory Solutions for Nut Stability
Spring washers are used in vibration situations, but the spring pad is not necessarily anti-loosening. Screws are easy to rust after aging, and the difficulty of disassembly is very large. There will be a certain gap between the screw of the elastic pad and the connected piece. The screws have axial preload, so the screws with elastic pads are relatively easy to remove after aging.
Key Functions of Flat Washers
The flat pad is not only used to prevent the spring pad from scratching the surface of the connected part. When the through hole of the connected part is larger than the nut, adding the flat pad can indirectly reduce the through hole and increase the force area to prevent the nut from entering the through hole.
If the connected part is a thin-walled part, the flat pad should be added to increase the force area and indirectly thicken the connected part to avoid the damage of the thin-walled part in the stress concentration through the hole.
Frequently Asked Questions
Q: Are spring washers completely anti-loosening in vibration situations?
While spring washers are commonly used in vibration situations, the spring pad itself is not necessarily anti-loosening.
Q: Why are screws with elastic pads easier to remove after aging?
Screws with elastic pads are relatively easy to remove after aging because there is a certain gap between the screw of the elastic pad and the connected piece, and the screws maintain an axial preload.
Q: What is the purpose of using a flat washer (flat pad) alongside a spring pad?
A flat washer is primarily used to prevent the spring pad from scratching the surface of the connected part during assembly and use.
Q: How do flat washers help when the connected part's through hole is larger than the nut?
Adding a flat washer indirectly reduces the size of the through hole and increases the load-bearing force area, preventing the nut from slipping into or through the hole.
Q: Why should you add a flat washer to thin-walled connected parts?
For thin-walled parts, a flat washer should be added to increase the force area and indirectly thicken the connection. This avoids structural damage to the thin-walled part caused by stress concentration around the through hole.
