Customization Options:
Request custom inner/outer diameters, material grades (410 or duplex stainless steel), or non-magnetic finishes.
Sizes range from M5 to M30, with optional passivation treatments to improve surface hardness. These washers are compatible with DIN, ASTM, and JIS fastener systems, ensuring global applicability.
Our various style Flat Washers exceed ISO 3506-7 and ANSI B18.22.1 standards, providing unmatched load distribution and vibration resistance. The thickened design (1.5–3 mm) enhances durability under high-pressure applications, preventing bolt loosening and material deformation.
