Description
DIN 557 Square Nut M8 – A2 Stainless Steel for Photovoltaic Structures
DIN 557 square nut M8 made of A2 stainless steel (1.4301), designed for mounting support structures in photovoltaic installations. The square shape of the nut ensures reliable locking of bolted connections and prevents the element from rotating within the mounting profile.
The product is manufactured in accordance with the DIN 557 standard. Austenitic steel A2 – 1.4301 (grade 304) is non-magnetic, flexible and resistant to stress. The addition of nickel to the alloy provides exceptional corrosion resistance, making the nut suitable for use in all weather conditions — both on roofs and in ground-mounted installations.
