DSH 16 series

Handschrauber DSH 26

The minia­tu­ri­sa­tion of many products is a parti­cular chall­enge in manufac­tu­ring – especi­ally in the process-safe assembly. We there­fore have developed the DSH 16 nutrunner for very low torques. The DSH 16 may be used for hand-guided opera­tion as well as for automated processes. Available in torque versions of 0.25 Nm and 0,5 Nm.

  • Status indicator via light field
  • Motor-gear combi­na­tion
  • Freely confi­gurable opera­ting buttons
  • Ergonomic handle
  • Headlight for illumi­na­tion of the application
  • Vacuum connec­tion for option “vacuum screw holder”
  • Suspen­sion clip
