Washer M30 DIN 125 A2 140 HV 31
Description
Flat Washer M30 DIN 125 A2 – Stainless Steel, Type A Plain
Flat Washer M30 DIN 125 A2 is a reliable fastening component manufactured from A2 stainless steel. An ideal solution for installers seeking durable, corrosion-resistant components for both outdoor and indoor applications.
Why A2 stainless steel? A2 material (equivalent to AISI 304) provides excellent resistance to rust and atmospheric corrosion, making this washer ideal for long-term use even in the most demanding weather conditions. A hardness of 140 HV guarantees high resistance to deformation and even distribution of clamping forces.
Compliance with DIN 125 ensures standardised dimensions and tolerances, providing full compatibility with M30 metric bolts and nuts. The washer is reusable and fits all standard M30 bolted connections.
