Features

Features:

The Gedore Torque QSN 40 FH Ergo Quickset is an ultra-precise, micro-torque adjustable screwdriver specifically designed for extremely delicate assembly tasks. Operating within an ultra-fine calibrated range of 8 to 40 cN·m (0.08 to 0.4 N·m), this screwdriver allows operators to make rapid, exact torque adjustments on the production line without requiring external calibration setups.

Featuring an internal torque-limiting slipping clutch and a clear micrometer scale, the QSN 40 FH disengages automatically once the target torque limit is met, eliminating any risk of over-tightening or stripping fine component threads. Weighing only 159 grams, its lightweight build and ergonomic handle offer unmatched tactile control and high repeatability (±6%), making it the gold standard for micro-electronics, sensitive PCB assembly, optical equipment, and medical devices.

Key Benefits & Features

  • Ultra-Low Micro-Torque Precision: Operates in the sensitive 8 – 40 cN·m range, delivering exact tightening control for miniature fasteners and fragile assemblies.
  • Calibrated Quickset Scale: Built-in micrometer scale permits fast, precise, and repeatable torque adjustments directly on the shop floor.
  • Zero Over-Tightening: The precision slipping mechanism disengages automatically at the set limit, making over-torquing and thread stripping impossible.
  • Featherweight Ergonomic Handle: Weighing just 159 g, it drastically reduces wrist strain during high-volume, repetitive micro-assembly shifts.
  • Universal 1/4″ Hex Receiver: Compatible with all standard 1/4” driver bits for maximum operational versatility across tasks.
  • Built for Industrial Longevity: Robust internal engineering guarantees long service life and reliable repeatability (±6%) under continuous daily duty.

    Industry Applications
  • Electronics & Micro-Semiconductors: Micro-fasteners on PCBs, mobile hardware, sensors, and delicate electronic enclosures.
  • Medical Devices & Scientific Instruments: Surgical apparatus assembly, laboratory diagnostic tools, and optical mountings.
  • Aerospace & Defense Avionics: Precision cockpit instruments, delicate sensor wiring, and circuit housing.
  • Horology & Fine Mechanics: Precision watchmaking hardware, small optics, and micro-electromechanical systems (MEMS).
