NF E 25-511 Conical Knurled Spring Washers – High-Tension Locking Washers for Vibration and Load Stability

Description

The NF E 25-511 Conical Knurled Spring Washer is specifically designed to provide enhanced load distribution and vibration resistance in critical bolted assemblies. Its conical shape and knurled surface deliver superior locking capability, making it ideal for dynamic load environments and applications where fasteners are prone to loosening.

These washers are available in carbon steel and stainless steel, providing both strength and corrosion resistance. Multiple finish options—including plain, black oxide, zinc electroplating, hot dip galvanizing, copper plating, nickel plating, and zinc impregnation—allow these washers to be tailored for use in diverse industrial conditions.

Conforming to NF E 25-511 specifications, this washer also aligns with other international standards such as GB, DIN, ISO, ANSI/ASTM, BS, and JIS. OEM services are available for custom shapes, sizes, and finishes based on your drawings or product samples.
