Disc spring washers are Boltead’s main product. We are a manufacturer of disc spring washers and also a supplier of disc spring washers. While producing and supplying lat washers, we also produce bolts, nuts and other fastener products used in conjunction with them.
The disc spring washers we produce are generally classified according to whether the material is carbon steel or stainless steel. More specific classifications are as follows:
There are three common classification methods for washer grades.
Washers can generally be classified according to material, such as carbon steel washers and stainless steel washers.
There are also classifications based on use, shape and size, such as Class A, Class C, etc.
In addition, some washers have strength levels, such as spring washers, which are divided into levels 4.8, 8.8, etc.
In addition to different materials and strengths, the biggest impact on disc spring washers is surface treatment. The following are the more common surface treatments for disc spring washers: black oxide, black zinc, zinc plated (ZP), color zinc plating (CZP /YZP), hot dip galvanized (HDG), dacromet coating, etc.
disc spring washers are sent from the raw material line to the final product. They generally go through the following process:
Annealing of raw materials – pickling – drawing – forming – grinding – heat treatment – surface treatment – classification – packaging – shipping
The rough schematic diagram is as follows:
