Product overview Handheld Screwdrivers
In today’s precision manufacturing and assembly industries, maintaining strict control over torque, accuracy, and operational efficiency is essential to ensure product quality and reliability.
The JIT Handheld Screwdrivers – BFG Series is purpose-built for micro-torque fastening applications, offering a working range of 0.15 – 1.0 kgf·cm for high-precision assembly tasks.
Equipped with advanced gyro stabilization, interchangeable attachments, and an intelligent feedback system, the BFG series provides consistent, repeatable, and error-free screw tightening performance.
This makes it ideal for use in electronics, optical instruments, and micro-mechanical component assembly, where precision and repeatability are critical.
Key Features and Technologies
- Gyro-Stabilized Operation: Integrated gyroscopic stabilization ensures smooth torque output, vibration suppression, and ergonomic handling across all models — including Standard, LED, Z, EZ, Z+LED, and EZ+LED configurations.
- Digital LCD Feedback: Real-time display of torque values, OK/NG results, screw count, and tilt angle. Equipped with visual and audible alarms for tightening confirmation and error alerts.
- Versatile Power Supply: Supports 100–240 V AC input, internally converted to 9–19 V DC, allowing flexible installation and use in different production environments.
- Programmable Tightening Sequences: Allows up to five consecutive torque cycles per operation, increasing productivity and process consistency for repetitive assembly tasks.
- External Control Integration: Compatible with external Power-On inputs and motor stop signals, enabling seamless automation and synchronization with robotic systems or workpiece detection triggers.
