(Also known as Battery-Powered Torque Screwdriver / Cordless Precision Screwdriver)

A cordless torque-control screwdriver is a battery-powered precision fastening tool designed to apply accurate, consistent torque to screws and small fasteners. Unlike standard cordless screwdrivers, this tool incorporates electronic torque measurement, control algorithms, and brushless motor technology to ensure that each fastening meets precise torque specifications.

It is widely used across industries, including electronics assembly, appliance manufacturing, automotive interiors, medical devices, aerospace components, and Industry 4.0 production lines.

Key Features

1. Precision Torque Control Technology

• Torque is regulated by electronic feedback loops, not just mechanical clutches.

• Ensures ±3% or better repeatability

• Real-time torque monitoring for quality assurance

• Supports soft joint and hard joint fastening profiles

2. Brushless DC Motor (BLDC)

• High efficiency with low heat

• Longer lifespan (no brushes to wear out)

• Smooth torque delivery for delicate assemblies

3. Programmable Torque Settings

• Multiple torque presets are stored inside the tool

• Fast switching for mixed-model or multi-station assembly

• Digital torque modes:

  • Angle + Torque

  • Torque Only

  • Final Torque + Seating Detection

4. Smart Electronics & Protection

• Overheat, overload, and stall protection

• Electronic brake for immediate stop

• Auto shut-off when target torque is reached

5. Lithium-Ion Battery Platform

• 18V / 20V or compact 12V systems depending on model

• Long runtime for continuous production

• Quick-swap battery design minimizes downtime

6. LED Work Light & Ergonomic Design

• Illuminates the fastening area

• Balanced grip reduces operator fatigue

• Low vibration for precision work

✔ Ideal for mobile or overhead assembly stations

✔ No cables → safer, cleaner workstations

✔ Supports Industry 4.0 data logging (optional with wireless modules)

OEM / Engineering Design Considerations

1. Torque Range & Accuracy

• Choose torque ranges (e.g., 0.5–3 Nm, 2–9 Nm, 5–15 Nm)

• Verify accuracy based on application criticality.

2. Motor & Gearbox Optimization

• Low-inertia BLDC motor for fast response

• Precision planetary gearbox for torque stability

3. Electronic Torque Control Board

• MCU with torque-angle algorithms

• Support for factory-level settings lockout

• Optional wireless communication (BLE/WiFi) for torque data

4. Power System

• Battery voltage choice impacts torque capability

• Temperature management around the battery and the ESC is critical

5. Ergonomics & Assembly Safety

• Handle angle and grip contour

• Safety certification options (CE, UL, ESD-safe housing)

Product Configurations

• Bare Tool

• Starter Kit (Tool + Battery + Charger)

• Full Assembly Kit (Multiple bits + torque rings + case)

• Smart Factory Kit (Wireless module for torque reporting)
