Two Layer Self Locking Washer

The two layer self locking washer is made from stainless steel or carbon steel. That means it holds up well over time and doesn’t rust easily. The top part uses spring steel, so it stays bendy and flexible. The bottom has small teeth that dig into the thing you’re fastening, which helps keep it locked in place. If you’re using it in rough conditions, there are versions with extra coatings,like zinc or phosphate to make them tougher.

Thanks to this combo of materials, the two-layer self-locking washer can take crazy amounts of pressure,we’re talking up to 1,200 MPa without warping or snapping. That’s why they’re used in critical spots where reliability matters, like on boats, in chemical plants, or outdoor equipment that faces tough weather.

Application

The two layer self locking washer in machines that shake a lot,think engine mounts, conveyor belts, or wind turbines. They’re good at staying put even when things get rattled. They’re also key for stuff that really can’t afford to come loose, like car suspensions, train parts, or factory robots.

Double Layer Self Locking Washers are used in electrical panels, AC units, or solar/wind setups where connections need to stay tight despite heat swelling or sudden bumps. Basically, anywhere things need to work reliably,like your washing machine or a plane’s hydraulic system,these washers stop them from breaking down when you can’t afford for things to go wrong.

Materials

Q: What materials are used for these washers, and how do they handle rust-prone areas?

A: These Double Layer Self Locking Washers are usually made of stuff like stainless steel (think SS304 or SS316), carbon steel with zinc/DACROMET coatings, or heavy-duty alloys like Inconel. Stainless steel versions don’t rust easily, so they’re solid for damp or salty places. Carbon steel ones are cheaper but get a rust-fighting boost from those coatings.

If things get really nasty,like chemical plants or ocean equipment—Inconel’s your pick because it laughs off heat and harsh chemicals. Basically, your material choice decides how long the washer lasts, how much load it can take, and whether it’ll survive the environment you throw it into. That way, the two layer self locking washer stays put even in rough conditions.
