Description
Spring Washer DIN 7980 A2 M8 – Stainless Steel 1.4301
Spring washer DIN 7980 made of A2 stainless steel (1.4301, grade 304) ensures a secure connection and constant tension in bolted joints. Its spring action compensates for thermal changes and prevents loosening of the connection due to temperature fluctuations or vibration — which is particularly important in photovoltaic installations exposed to variable weather conditions.
Properties of A2 – 1.4301 (grade 304) steel
- Austenitic stainless steel (non-magnetic), flexible and stress-resistant
- Exceptionally strong corrosion resistance thanks to the addition of nickel to the alloy
- Suitable for all environmental conditions
