Double Layer Self Locking Washer

The double layer self locking washer is designed to keep bolts from coming loose during vibrations or movement. It has two parts, a flexible steel top layer and a bottom layer with teeth. Together they create enough friction to lock things in place.

The double-layer self-locking washer keeps bolts secure for longer without needing adhesives or extra components. The two-layer setup spreads out the pressure better, so it's less likely to damage whatever surfaces you're fastening. Normal washers don't work like this.

The double-Layer Self-Locking Washer is useful in tough conditions where things get shaken around a lot, and works as a budget-friendly option for industries like car manufacturing, airplanes, and heavy equipment that need hardware that stays put.

Features

The double-layer self-locking washer is good at handling vibrations and can be reused multiple times. Its two-layer setup keeps bolts secure even if temperatures shift or things start to rust. You don’t need extra stuff like special nuts or locking glue with it—this makes putting parts together simpler and saves money on buying extra components.

The double layer self locking washer meets common industry standards (like ISO and DIN) and keeps its grip even when under repeated pressure. Engineers use it in all kinds of places, like electric motors or construction projects, because it helps prevent parts from failing and cuts down on repair work.

Double-layer self-locking washers have advantages over ordinary washers

Q: How does this double-layer self-locking washer lock by itself, and why is it better than normal washers?

A:Double-layer self-locking washers have two layers,the top has little teeth, and the bottom has ridges that lock together. When you tighten the bolt, the top teeth dig into whatever you're attaching it to, while the bottom layer pushes back against the bolt/nut. This combo stops vibrations or movement from loosening things the way regular washers eventually would.

This two-layer design keeps the connection tight without needing glue, lock-tight chemicals, or other extra stuff. Unlike regular flat washers, it doesn’t let bolts come loose over time. That means you don’t have to check or fix them as often, and you can reuse the washer in many cases. The double layer self locking washer works well for cars, machinery, airplanes, and other places where things vibrate a lot or need to stay secure long-term.
