Ultra-wide precision torque range: Features a unique, continuous torque range from 0.1 kgf·cm to 20 kgf·cm, enabling precise fastening of micro-screws (sizes M0.6–M3) and perfectly meeting assembly requirements for ultra-precision components such as smartphone camera modules, Bluetooth headsets, and smartwatches.

Ultra-precise torque control: The entire series utilizes a stepped fine-adjustment mechanism, ensuring linear, stable torque output without drift. This fundamentally eliminates issues such as screw stripping, breakage, floating screws, and component damage, thereby guaranteeing high product yields.

Fully customizable chuck design: Supports custom chuck specifications to meet unique client requirements regarding size and interface; compatible with various non-standard bits and specialized assembly processes, overcoming compatibility limitations associated with generic chucks.

Intelligent multi-speed matching: Models SWZ-300L/400L feature dual-speed modes (1000/2000 rpm)—high speed for rapid pre-tightening to boost efficiency, and low speed for precise final fastening control. Other models operate at a standard precision speed of 1000 rpm, ensuring stable and controllable operation.

Production line compatibility: The entire system operates on a DC48V input and utilizes a lever-start mechanism, making it easy to learn and operate. It integrates seamlessly into existing automated production lines and manual assembly stations, reducing costs associated with line modification and personnel training.
