I needed a few eight millimeter flat washers to put together a tractor part. It was cheaper to purchase in bulk than just a few at the local hardware store. These washers were nice and shinny stainless steel washer. Stainless should not rust. They fit the M8 bolt I had nicely. I was always taught when using a lock washer to have a washer under the lock washer to ensure it will stay tightened and last for a long time.

I rarely leave reviews, but I felt compelled to write one for this product because it has truly impressed me. From the moment it arrived, I could tell it was well-made and of high quality. The packaging was secure, and everything was neatly arranged, which was a great start. What really stood out to me was how easy it was to use. Whether you're familiar with products like this or it's your first time, you'll have no problem figuring it out. The setup was quick, and it worked exactly as described. I’ve been using it consistently since it arrived, and it hasn’t let me down once. The performance is outstanding. It delivers exactly what you need and more. One thing I particularly appreciate is how reliable and efficient it is. It has quickly become something I reach for regularly, and I can already tell it’s built to last. Durability is another major plus. It feels sturdy and well-constructed, so I have no concerns about it holding up over time. I’ve accidentally put it to the test a couple of times, and it has proven to be tough and long-lasting. For the price, I couldn’t ask for more. I’ve seen similar products that cost much more but don’t offer the same level of performance or reliability. This one strikes the perfect balance between affordability and quality. Customer service has also been top-notch. The company clearly stands behind their product and is available to answer any questions you might have. It’s always great to know there’s support available if you need it. In conclusion, I’m extremely happy with this purchase. It has exceeded my expectations in every way, and I can confidently recommend it to anyone. Whether you’re looking for something practical, reliable, or just a great value, this product is the perfect choice. I’m sure it will serve you well for a long time.

The product arrived nicely packaged and clearly marked in a zip-lock storage bag. The stainless finish makes for a neat / professional appearance of the final project. I was surprised to get stainless grade for the low price I paid.

These are simple stainless steel washers for a project. They are as described, work well, and arrived as scheduled. This is why I keep shopping Amazon which is both faster and more satisfying than searching my local hardware store.

They're flat washers and they're stainless and they were the right size. And, way less expensive than my local hardware store.

These are well made washers that will probably do their job to the last one.
