In many industrial designs, creating a classic internal thread increases production time and assembly costs. Therefore, it is increasingly used self-forming screws thread DIN 7500, which independently form a thread in the material when screwed in.

This solution allows for a durable and strong connection without the need to pre-thread the hole.

DIN 7500 screws

DIN 7500 is a standard for self-threading screws intended mainly for:

• steel,
• sheet metal,
• aluminum,
• non-ferrous metals.

Key features:

• no need to thread the hole,
• quick assembly,
• high connection strength,
• possibility of repeated assembly and disassembly.

Eurobolt offers 4 variants of these screws.

How do thread-forming screws work?

DIN 7500 screws do not cut material like classic self-tapping screws.

Instead:

1. deform the material,
2. form threads when screwing in,
3. create a durable, high-strength connection.

This makes the connection stronger and more resistant to tearing.

The most important advantages of DIN 7500 screws

No threading required

There is no need to make a separate thread in the material.

This means:

• faster assembly,
• lower production costs,
• fewer technological operations.

High connection strength

The thread forming process causes:

• better thread fit,
• larger contact surface,
• high resistance to tearing.

Possibility of multiple installations

The connection can be:

• unscrew,
• turn again,
• service.

This is a big advantage over many classic sheet metal screws.

Reducing material damage

No cutting process means:

• less material weakening,
• no chips,
• greater durability of the connection.

Where are DIN 7500 screws used?

Self-threading screws are used in many industries.

Most common uses:

• machinery industry,
• steel structures,
• electronics and housings,
• automotive,
• industrial equipment,
• assembly of sheets and profiles.

Protective materials and coatings

DIN 7500 screws can be made of:

• hardened steel,
• galvanized steel,
• stainless steel.

Protective coatings increase resistance to:

• corrosion,
• moisture,
• industrial conditions.

When is it best to use self-forming screws?

This solution is especially useful when:

• quick assembly is important,
• a permanent connection is required,
• there is no possibility of making threads,
• the connection will be serviced multiple times.
