Robust and reliable fastening

The stainless steel A2 hex bolt DIN931 M12x80 is designed for strong and durable connections in various applications. Thanks to the hexagonal head, you can easily tighten the bolt with a standard open-end or socket wrench, ensuring efficient assembly.

High-quality materials and corrosion resistance

This bolt is made from A2 grade stainless steel, also known as 304 stainless steel. This material offers excellent corrosion resistance under normal atmospheric conditions, in wet environments, and when exposed to oxidizing and organic acids. This makes the bolt suitable for both indoor and outdoor applications.

Applications in the automotive sector

In the automotive sector, it is essential to rely on the quality and durability of fastening materials. The stainless steel A2 hex bolt M12x80 is ideal for mounting parts exposed to moisture and varying weather conditions. Examples include:

• Fastening of body parts
• Assembly of exhaust systems
• Installation of suspension components

Advantages of partial threading

The DIN931 standard refers to a hex bolt with partial threading. This design offers specific advantages:

• Higher tensile strength: The unthreaded part of the bolt provides a stronger connection, which is especially important in high-load applications.
• Better alignment: When assembling parts, the smooth section of the bolt helps to align the components accurately.

Compatibility with other fasteners

For optimal fastening, it is recommended to combine the stainless steel A2 hex bolt with matching nuts and washers of the same material and quality. This prevents galvanic corrosion and ensures uniform strength and corrosion resistance of the entire connection.

Maintenance and lifespan

Stainless steel A2 requires minimal maintenance and retains its properties over a long period. However, regular inspection of the fasteners is recommended to ensure the safety and reliability of the construction.
