1. What does the DIN 7340 standard mean?

DIN 7340 is a German industrial standard that defines the dimensions, tolerances, and materials for tubular (hollow) rivets. It ensures reliability, quality, and compatibility in industrial applications.

2. What materials do you use for the rivets?

We use brass, copper, aluminum, steel, and stainless steel. Upon request, we can also provide surface treatments such as zinc plating, tinning, nickel plating, etc.

3. Do you also offer custom-made products?

Yes, we manufacture tubular rivets in non-standard dimensions based on the customer’s drawing or sample.

4. What are the typical dimensions of rivets?

Outer diameter: 1–15 mm, wall thickness: 0.15–1 mm, length: up to 200 mm.

5. Where are tubular rivets most commonly used?

In the automotive, electrical, furniture, textile, and packaging industries.

Tubular Rivets

Description and Features:

Tubular rivets are manufactured from precision-drawn capillary tubes and conform to DIN 7340. They serve as ideal fasteners across automotive, electrical, medical, and furniture industries. At Rona Kranj, our rivets are produced from various non-ferrous metals to meet the highest technical standards, employing specialized machinery to ensure precise dimensions and quality.

Rivet Forms:

Form A – Flat Head Tubular Rivet

Characterized by a flat top and uniform cylindrical shaft dimensions, offering consistent wall thickness.

Form B – Rolled Round Head Tubular Rivet

Features a semi-spherical head formed with precision tooling, offering enhanced aesthetic appeal.

Form C – Countersunk Head Tubular Rivet

Designed for flush mounting, facilitating seamless surface integration and finishing.

Dimensions:

Outer diameter: 1 mm – 15 mm

Wall thickness: 0.15 mm – 1 mm

Length: up to 200 mm

All measurements and tolerances comply with DIN 7340.
