Description
Flat washer DIN 125 M16 stainless steel A2 – ⌀17 mm for PV installations
Flat washer DIN 125 M16 made of A2 (1.4301 / grade 304) stainless steel is an essential component of every bolted connection in photovoltaic structures. The hole diameter of ⌀17 mm and outer diameter of ⌀30 mm ensure even distribution of pressure over the contact surface, protecting the mounting profile from deformation and preventing the connection from loosening. Austenitic A2 stainless steel guarantees exceptional corrosion resistance — the washer retains full functionality throughout the entire service life of the installation, regardless of weather conditions. The material is non-magnetic, flexible and stress-resistant, making it perfectly suited for use with stainless steel bolts and nuts in connections exposed to vibration and variable thermal loads.
Advantages of the A2 DIN 125 M16 washer
- Evenly distributes the pressure of the M16 bolt over a larger surface area, minimising the risk of substrate deformation
- Austenitic 1.4301 stainless steel with added nickel provides long-lasting corrosion protection in all environmental conditions
- Compliance with the DIN 125 standard guarantees dimensional consistency and full interchangeability with other fastening components
- Proven in PV mounting systems — ideal for bolted connections in ground-mounted and roof-mounted structures
- 3 mm thickness ensures stable clamping force and compensates for surface irregularities
