Wholesale Fe6 Spring Washers - Zinc/HDG/Phosphate Coated Railway Hardware Parts

The Fe6 Spring Washers are precision-engineered components designed for demanding railway and industrial applications. These washers are manufactured using premium 65Mn steel material, ensuring exceptional durability and performance under heavy load conditions.

Our spring washers feature a double coil design that effectively compensates for material shrinkage and prevents radio interference caused by loose hardware. The unique construction provides superior tension maintenance and vibration resistance in railway fastening systems.

Available in multiple surface treatments including plain, phosphate, black oxide, and hot-dip galvanized (HDG) finishes, these washers offer excellent corrosion resistance for outdoor applications. The standard hardness range of HRC43-49 ensures optimal spring performance and longevity.

These industrial-grade spring washers undergo strict quality control measures to meet international railway standards. The compression performance is guaranteed with minimum height of 17.80mm under 40kn load for 10 seconds, making them suitable for heavy-duty applications.
