Product Description

Before a batch of nord lock inspired double ended self locking washers leaves the factory, they get one last look to make sure they’re all good. Workers first check for any obvious problems—like dents, scratches, or ends that aren’t bent right.

Then they measure things like the overall width, the hole size, and thickness to be sure they match the order specs. They also test how well the washers lock by tightening them onto bolts and trying to shake them loose.

For bigger orders, they don’t test every piece—just random samples from the batch. Some places even use machines to check lots of washers fast.

Only after passing these checks do the washers get shipped. This final step helps make sure customers get washers that work properly with no issues.

Quality Certification

Nord lock inspired double ended self locking washers often include quality certificates to confirm they meet accepted standards. A typical one is ISO 9001, which shows the manufacturer follows a solid quality management process.

Many suppliers also provide material certs—like RoHS (which means no restricted materials) or REACH (meeting EU chemical regulations). These aren’t just paperwork—they come from independent groups that have verified the production process.

Suppliers keep these certificates current, normally updating every 1 to 3 years.

For customers in areas like aerospace or medical devices, these docs are especially important—they help show the washers are suitable and dependable for critical applications. Even for general industrial use, having these certificates gives buyers more trust that the washers are made to global standards.
