Washer M6 DIN 125 A2 140 HV 6.4

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 ensures high resistance to deformation and an even distribution of clamping forces.

Compliance with DIN 125 means standardised dimensions and tolerances, ensuring full compatibility with M6 metric bolts and nuts. The washer is reusable and fits all standard M6 bolted connections.
