The HFC3000II is a handheld electric tightening system (hand held nutrunner) that controls the tightening result by torque or angle setting and monitors the tightening process against torque, angle, time and other criteria. The pistol grip tool has a built-in gyroscope for ergonomics and safety, and reverse rotation combined with vibration-sensing thread engagement reduces cross-threading and damage to threaded holes. It accepts a wide 100–240VAC input and stores 12,000 result records, 100 curves and 500 error records.

Typical Applications
High-torque handheld tightening
A handheld electric tightening system that controls the tightening result by torque or angle setting, suited to assembly stations that require higher torque, such as automotive and heavy machinery.
Work where reaction force must be avoided
The Straight Tool eliminates reaction force with a telescopic torque tube and starts automatically when pressed onto the screw. It can be used horizontally or vertically, reducing operator strain.
Tightening in narrow or restricted spaces
Angle tools are available for tightening positions with adjacent-part interference, narrow spaces or limited access angles.
Preventing cross-threading and threaded hole damage
Reverse rotation with vibration-sensing thread engagement first turns backward to find the thread start, then tightens forward; the tightening status is indicated to the operator by both LED and sound.
Frequently Asked Questions
How do I choose between the three HFC3000II tool types?
The Straight Tool (push-to-start) uses a telescopic torque tube to eliminate reaction force; it starts automatically when pressed down onto the screw, can be used horizontally or vertically, and is available with an optional high-speed shock absorber; model HFT-030M80-DP-H. The Pistol Grip Tool features an ergonomic, high-speed and lightweight design with a built-in motion (gyroscope) sensor for safer operation; models include HFT-015M50-P1, HFT-035M80-P1, HFT-035M80-P1-X and HFT-060M80-P1-X. The Angle Tool is suited to tightening in narrow spaces and restricted positions. For the maximum torque, torque range, speed, length and weight of each model, please refer to the catalog or contact our sales team.
How does the HFC3000II prevent cross-threading and damaged threaded holes?
It uses reverse rotation combined with vibration-sensing thread engagement: it first rotates in reverse to find the start of the thread, then rotates forward to drive the screw in, reducing cross-threading and damage to threaded holes. For tightening control, judgment conditions can be set by torque or angle, and the tightening process is monitored and checked against conditions such as torque, angle and time; the tightening result is indicated to the operator with both visual (LED) and audible signals.
How much tightening data can the HFC3000II store? Can it connect to host systems?
It stores 12,000 result records, 100 curves and 500 error history records. Multiple sets of control parameters can be configured from a PC over standard Ethernet, and a range of industrial communication protocol modules are available, such as CC-Link V1/V2, DeviceNet, PROFIBUS-DPV1, PROFINET I/O and EtherNet/IP, to improve the reliability of quality control. With the optional CF card slot (model Option3) on the controller, large amounts of data, including quality data, can be stored on a CF memory card even when no PC is connected.
What are the power requirements of the HFC3000II, and how well does it adapt to the shop floor?
It supports a wide voltage range of 100~240VAC, making it easier to deploy at overseas plants or sites with varying power conditions. The tool body has a dust-proof and oil-proof design for production line environments. The controller also has a built-in simple sequence function for batch counting and multi-parameter switching, handling common multi-station tightening workflows without a separate PLC.
How is the HFC3000II different from an ordinary handheld electric screwdriver or torque screwdriver?
Ordinary handheld electric screwdrivers (often called torque screwdrivers) set torque with a mechanical clutch that slips and stops at the set value, so accuracy depends on clutch wear and you cannot tell how far each screw was actually tightened. The HFC3000II controller judges each result by torque or angle, signals OK/NG with LED and sound, stores 12,000 results and 100 curves, and connects to MES, making it suited to high-torque handheld stations that need tightening records.
