Product Description

The main good thing about maintenance free two fold self locking washers is that they’re really good at not letting things loosen up from vibrations—better than a lot of regular lock washers. They lock things in place with a mechanical hold, not just relying on the friction between threads. Putting them together is easier than using chemical glues or those more complicated locknuts. Also, these washers keep a good grip on the parts they’re holding, and in some cases where it’s not super critical, you can even reuse them.

Applicable Scenarios:

Maintenance free two fold self locking washers are really useful in industries where things shake a lot. Like, in cars—for engines and suspensions. In planes, too—for the airframes and engines. They’re good in heavy machinery, like construction or farm equipment. Also in trains, and industrial gear such as pumps, compressors, and generators. Any situation where a loose bolt could cause a big breakdown or safety problems is a perfect spot for these maintenance free two fold self locking washers.
