Stainless steel grounding washer 40x40mm with 10.4mm hole – A2

Compact stainless steel washer 40×40 mm with sharp spikes ensures reliable grounding connection between the panel frame and profile with surface treatments such as anodizing or powder coating. Thanks to the hole with a diameter of 10.4 mm, it is compatible with standard fasteners and allows for easy installation. It is inserted between the panel frame and profile, where the spikes disrupt the surface layer and ensure conductive contact. Ideal for photovoltaic installations with an emphasis on safety and standards.
