High-speed joining


High-speed joining without pre-punching. With RIVTAC® tack setting for several materials.


High-speed joining

RIVTAC® joins diverse materials in record-breaking time.

Position, set tack, done. And repeat. RIVTAC® allows joining without pre-punching in very short cycle times. Even if the component is only accessible from one side.

This product is made by Böllhoff

Method / principle

Easy and quick. High-speed joining with RIVTAC® occurs in just one operation. The tack penetrates the components and joins them efficiently together without the need for pre-punching.


RIVTAC® is particularly suitable for joints of aluminium, steel, plastics, non-ferrous metals as well as for mixed joints, multiple-layer joints and hybrid joints of these materials.

Product benefits
  • Joining without pre-punching in case of one-sided accessibility
  • Reduction of joining and cycle times to a minimum
  • Joining of high-strength materials
  • Flexible application for mixed joints, multiple-layer joints and hybrid joints
  • Optimal possibility of combining with adhesion technology

Product benefits

There are many good reasons for using our products.

Strength and options.
Point by point.

Joining from one side without pre-punching

Fast and efficient. The solution for hollow bodies, housings or components with one-side accessibility.

Reduction of joining and cycle times to a minimum

While one tack is set, the next is positioned. Ready for operation in 0.9 to 1.5 seconds.

Wide range of applications

Ideal for mixed, multilayer or hybrid joints, which are becoming increasingly important in the development of modern vehicle and car body designs.

Detailed description


Fast and effective

The tack penetrates the materials of the components to be joined at high speed. A momentary rise in temperature in the joining zone and the resulting improved flowability causes the parent material to be displaced into the annular grooves on the shank of the tack. The result: a high form fit and – especially for higher-strength steel materials – a non-positive connection due to pressing and compression of the material.
