High Strength Spring Washers from China - Reliable Suppliers & Quality Factory Products 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.
Spring Washer Mechanics
Maintains axial preload to create a gap between the screw and the connected piece, facilitating easier removal and disassembly even after aging and rusting.
Flat Washer Functions
Prevents surface scratches, increases force distribution area, reduces through-hole clearance, and protects thin-walled parts from stress concentration damage.
In addition, 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
Are spring washers completely anti-loosening in high-vibration environments?
While spring washers are commonly used in vibration situations, they are not necessarily fully anti-loosening. However, they provide critical axial preload to the assembly.
Why are screws with elastic pads easier to remove after aging?
Screws with elastic pads have an axial preload that maintains a small gap between the screw and the connected component. This gap makes disassembly significantly easier even when the screws rust over time.
What is the purpose of using a flat washer?
A flat washer is used to prevent the spring pad from scratching the surface of the connected part, increase the force-bearing area, and reduce the effective size of oversized through-holes.
How do flat washers prevent nuts from falling through oversized holes?
When the through-hole of a connected part is larger than the nut, adding a flat washer indirectly reduces the hole size and expands the force area, stopping the nut from slipping into the hole.
Why should flat washers be used on thin-walled parts?
For thin-walled parts, adding a flat washer increases the load-bearing area and indirectly thickens the component. This prevents damage caused by stress concentration around the through-hole.
