DSH 16

Handschrauber DSH 26

The minia­tu­riza­tion of many products pres­ents a parti­cu­lar chall­enge for manu­fac­tu­ring – espe­ci­ally in terms of process-relia­ble assembly.

To meet this need, we deve­lo­ped the DSH 16 nutrun­ner for extre­mely low torque values, suita­ble for both hand­held use and inte­gra­tion into auto­ma­ted systems.

The DSH 16 series is available in torque versi­ons of 0.25 Nm and 0.5 Nm.
