Durable and rust-resistant
Using these on an outdoor gate mechanism. After six months of exposure to rain, there is absolutely no sign of rust. The 304 steel claim holds up.

Perfect fit for my project
Ordered the M6 size for a machinery repair. The quality of the stainless steel is excellent, and they fit perfectly without any slipping. Highly recommended for heavy-duty applications.

Sizes mixed in package
The quality is good, but the packaging was not clearly labeled, and I had to sort through to find the M8s I needed. Please improve labeling.

Professional grade quality
As a mechanic, I go through a lot of washers. These are consistent in thickness and springiness. Will definitely order again.

Essential for vibration control
These spring washers provide excellent tension. I use them on motor mounts where vibration is high, and nothing has come loose since installation.

Good value for bulk purchase
Bought a large pack of M4 washers. Most are perfect, though I found one or two with slight cosmetic imperfections. Functionally, they work great for preventing loosening.
Q: Can these be reused after removal?
A: While technically possible, it is generally recommended to replace spring washers after removal as they may lose some of their elastic tension and locking effectiveness.
Q: What is the difference between GB93 and DIN127 standards listed?
A: GB93 is the Chinese national standard, while DIN127 is the German standard. Both specify similar dimensions and performance criteria for spring lock washers, making them largely interchangeable for most applications.
Q: Do you sell individual sizes or only mixed kits?
A: We offer both options. You can select specific sizes like M2 or M10 individually from the dropdown menu, or choose our assorted kit which contains a variety of sizes.
Q: Are these washers suitable for marine environments?
A: Yes, if you select the 316 Stainless Steel option, they offer superior corrosion resistance suitable for marine and coastal environments.
Q: Is there a certificate of material analysis available?
A: Yes, for bulk orders over 5kg, we can provide a Mill Test Certificate (MTC) upon request to verify the 304 or 316 steel composition.
