ELECTRIC NUTRUNNER WITH MECHANICAL CLUTCH AND AUTOMATIC SHUT-OFF: OFFSET 90°
Brushless electric nutrunner designed and built entirely by Fiam in Italy. Compact 90° angle head for tightening in confined and hard-to-reach spaces. Mechanical clutch with automatic shut-off provides high repeatability and low Mean Shift across millions of cycles. Ergonomic reversible grip, low-effort lever start (9 N) and multifunction reversibility button with signaling LEDs make the tool suitable for continuous industrial use and Industry 4.0 environments.

Tool functionality with TPU-1 and TPU-2 power supply units
