Tightening technique

Built-in nutrunners DS series

Great products are the result of flawless processes. In the case of industrial manufacturing, perfect production is paramount.

Screw connections in particular should not cause product deficiencies. Digital tightening technique from DSM is a solid choice for high quality.

All DSM products are characterised by their perfect integration into new or existing production lines.

The DSM experts for built-in tightening technique support projects of our customers, from the planning phase, through to commissioning and of course beyond.
