Stainless steel A2 nut M8 with serrated flange DIN 6923 PV-11-03

Durable and reliable fastening in photovoltaic systems and beyond

Stainless steel M8 nut with a serrated collar, manufactured according to DIN 6923 standard, is a key element ensuring stable and corrosion-resistant connections. It is ideal for professional photovoltaic installations – for mounting roof hooks and mounting triangles – as well as in the food and machinery industries. Made of A2 (1.4301) stainless steel, it guarantees long-term reliability even in harsh environmental conditions.

Design and application

The use of a collar with a notch significantly increases the stability of the connection and minimizes the risk of the nut loosening on its own due to vibrations or temperature changes. This is particularly important in installations exposed to dynamic loads, such as photovoltaic systems mounted on roofs. A2 (1.4301) stainless steel provides high corrosion resistance, which is crucial for the longevity of connections, especially outdoors.

Advantages and benefits

• Corrosion resistance: Made of A2 (1.4301) stainless steel, it provides long-term protection against the effects of atmospheric factors and aggressive chemicals.
• Connection stability: The serrated collar increases the contact surface and prevents loosening of the nut, guaranteeing a secure fastening.
• Versatility: Suitable for a wide range of applications – from photovoltaic installations to the food and machinery industries.
• Durability: Solid construction and high-quality materials ensure a long service life even in demanding working conditions.
• Easy installation: Standard M8 size and design facilitate quick and efficient installation.

A2 (1.4301) steel is an austenitic stainless steel, characterized by flexibility, resistance to stress and exceptional corrosion resistance due to the nickel content in the alloy. It is a material suitable for working in various environmental conditions, making it an ideal choice for outdoor applications and in aggressive industrial environments.
