Brushless Motor: Adopts a high-efficiency brushless motor to provide higher no-load speed and stronger working performance, with maintenance-free operation.

Energy Recovery System (Recuperation): Features regenerative braking energy recovery function, effectively extending battery service life.

High-Precision Sensors: Equipped with a rotary torque sensor and angle encoder, the torque accuracy reaches ±2.5%, the torque sensor precision is better than 1% of full scale, and the angle resolution is up to 0.1°.

OLED Display: Real-time visualization of fastening results (torque, angle, etc.) and tool status, providing intuitive guidance for operators to complete the process.

Multi-Color Status LEDs: Programmable as required, clearly visible from all angles.

Handle Vibration Alarm: Alerts the operator via vibration when an NOK (Not OK) status occurs.

Powerful Storage Capacity: Most models can store 100 independent programs and at least 150,000 fastening results (including torque/angle curves).

Smart Battery Management: Equipped with a battery level indicator and deep discharge protection function.

HST-Tool-Manager Software: Enables fast, intuitive programming via the USB port, supporting multi-step fastening (up to 6 steps).

Wireless Connectivity (Optional): Supports 2.4 & 5 GHz Wi-Fi data transmission, allowing connection to an HST controller.

Barcode Reading (Optional): Integrated barcode scanner that can read and process barcodes with up to 64 characters.

Redundant System: The EC2 series is additionally equipped with redundant torque reaction sensors, complying with VDI/VDE 2862 standards and suitable for all types of A, B, and C critical connections.

Automatic Evaluation: Supports OK/NOK fastening result evaluation and can directly check the performance of mechanical clutches.

Versatile Form Factors: Available in Pistol, Angle, and Straight tool configurations to meet different spatial operation requirements.

Ergonomics: Optimized handle design with various color index rings for easy identification of application areas or torque levels.
