Heavy duty Carbon Steel Flat Washers are widely used in heavy machinery. They are employed at bolted connections where a large bearing area is required. These washers are made of sturdy carbon steel and help reduce surface pressure. Our prices are very suitable for industrial customers. We have a tiered discount system - if the order quantity exceeds 100,000 pieces, you will receive the most favorable price. They usually have black oxide treatment or plain color treatment.

Q: What surface treatments do you have for your Flat Washers to keep them from rusting?
A: To stop rust, we offer different surface treatments for these Heavy duty Carbon Steel Flat Washers. The most common ones are zinc plating (electro-galvanizing) — that puts a good protective layer on them — and hot-dip galvanizing, which gives a thicker coating for use in harsh environments. Every treated Heavy duty Carbon Steel Flat Washer resists rust better, so it lasts a lot longer when used outdoors or in damp conditions.
