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.
