Good quality, fast shipping

Solid stainless steel feel. I bought the M4 size for a computer case mod. One washer had a slight imperfection in the coating, but overall great value.

Perfect for my motorcycle project

These black washers look fantastic on my custom bike build. The finish is even and they fit the M6 bolts perfectly without slipping.

Great for outdoor use

Using these on a garden trellis assembly. The black oxide coating seems durable against the elements so far. No rust after two months.

Exactly as described

Needed specific blackened washers to match my hardware kit. These are genuine 304 steel and the spring tension is just right.

Professional grade

I use these in my repair shop daily. They hold torque well and the black finish prevents glare under bright shop lights. Highly recommend.

Good assortment

Bought the mixed pack to have various sizes on hand. The M8 and M10 are very sturdy. Wish the packaging was a bit more organized by size.

5 FAQ

Q: Can I return the pack if I ordered the wrong size?

A: Yes, provided the package is unopened and the items are in original condition. Please initiate a return request through your order history page within 30 days.

Q: What is the thickness of the M5 washer?

A: The standard thickness for our M5 split spring washer is approximately 1mm, adhering to DIN 127 specifications.

Q: Do you offer bulk pricing for orders over 50 packs?

A: Yes, we offer tiered wholesale discounts for bulk orders. Please contact our sales team directly via the 'Contact Us' form for a custom quote.

Q: Are these washers suitable for marine environments?

A: While made of 304 stainless steel which offers good corrosion resistance, we recommend 316 stainless steel for direct saltwater exposure. These are ideal for general outdoor or indoor industrial use.

Q: Does the black coating wear off easily during installation?

A: The black oxide finish is durable, but some minor scuffing may occur if over-torqued or scraped against rough surfaces. Proper installation tools minimize this risk.
