Perfect fit for my project

Ordered the M6 size in 304 stainless. They fit perfectly and the spring tension is just right. Great quality for the price.

Mixed sizes in bag

The quality is fine, but my bag of M5 had two M6 washers mixed in. Not a huge deal for my use, but worth noting for precision work.

Good value bulk pack

Needed a lot of M4 washers for a fencing job. These worked well, though a few had slight cosmetic scratches. Functionality was not affected.

Sturdy and reliable

These lock washers provide excellent vibration resistance. I used them on a motor mount and everything stays tight.

Excellent corrosion resistance

Using the 316 grade for a marine application. No signs of rust after three months of exposure to salt spray. Highly recommended.
