You can get these aluminum washers color-matched to your existing parts or branded gear in pretty much any shade you want, which is a huge deal for equipment where visual consistency matters as much as function.
They fit across automotive assembly, wood construction, and chemical plant maintenance without a hiccup, and the anodized finish means they won't corrode even when exposed to harsh fluids or outdoor moisture day after day.
We stock sizes from M4 all the way up to M90, covering DIN, ANSI, and GB standard, so you can pull exactly what your engineering spec calls for — the round-hole design doesn't play games with fitment.
The 3.6 through 12.9 grade range gives you choices for light brackets or heavy-load joints, and I've seen these hold up way better than standard steel washers in outdoor rigs that get rained on constantly.
ISO9001 certification keeps the batch quality locked in, which matters when you're running high-volume production or sourcing repeat orders for maintenance cycles across multiple facilities.
We offer a range of standard anodized colors like black, red, blue, and gold, and can match custom Pantone colors. Custom colors may have a small setup fee and a slightly higher minimum order quantity, so just let us know your specific shade.
For standard sizes and colors, the MOQ is around 1,000 pieces. If you need a custom color or a non-standard size, the MOQ might be 5,000 pieces to cover the anodizing line setup.
Yes, we can provide a mill test report for the aluminum alloy and our ISO9001 certificate. Just specify that you need the documentation when placing the order, and we'll include it with the packing list.
For standard sizes like M10 in a common color, lead time is about 15–20 working days. Custom colors or larger sizes up to M90 might take 25–30 working days because of the anodizing process.
Yes, the anodized layer provides good corrosion resistance, making them suitable for chemical environments and moderate outdoor exposure. However, for harsh outdoor conditions with constant UV or salt spray, we recommend checking the specific anodizing thickness we can apply.
