Unshakeable Two Fold Self Locking Washers

Unshakeable two fold self locking washers are special fasteners made to stop bolts or nuts from coming loose because of shaking, temperature changes, or moving loads. They work in two ways to keep things locked tight against vibrations, and you don't need extra glues, messed-up threads, or other locking tools. This is precisely why they are indispensable for critical components in harsh environments—after all, safety and reliability are core requirements. These components not only effectively reduce maintenance frequency but also fundamentally mitigate the probability of failure, providing a solid foundation for stable equipment operation.

Product Details:

Unshakeable two fold self locking washers work because of their two-part design. One side has little ridges that dig into the surface it's paired with, like a bracket. The other side has raised, sloped parts or small wedges. When you tighten the fastener, these sloped parts push up the washer's inner tabs, creating a strong, steady spring-like pressure against the bolt or nut head. This two-way locking uses both friction and spring force to keep things from turning—better than most other ways.

How does the locking mechanism of your unshakeable two fold self locking washers actually work to prevent loosening?

Unshakeable two fold self locking washers have a two-ring setup that's not like the usual ones.The inner ring of the washer fits snugly against a fastener like a screw, while the outer ring presses firmly against the surface it's attached to. Together, these two parts create significant friction and a certain tension that prevents the fastener from rotating and coming loose even during vibrations. They work better than regular flat or spring washers.
