PRO-Z is a patented tightening module that integrates screws, tools, software, mechanism and automation control. In addition to adjustable rotational torque and graph output, the movement speed and pressure of the vertical Z axis can be synchronized with the tightening motion. It handles M0.6~M5 screws with a target torque of 10~3200 mN·m and an effective Z-axis stroke of 30 mm, and can be integrated into a robot arm or XY table via TCP commands from the robot controller.

Typical Applications
Screw tightening module on robot arms
Controlled by TCP commands from the robot controller, it can be integrated into robot arms, XY tables or custom platforms, handling M0.6~M5 screws with a target torque of 10~3200 mN·m.
Tightening with synchronized pressing control
The movement speed and pressure of the vertical Z axis are synchronized with the tightening motion, handling variables that conventional screw tightening machines struggle to control. Effective Z-axis stroke: 30 mm.
High-repeatability tightening in mass production
In testing with M0.8 screws, it performed more than 1,200 consecutive tightening and loosening cycles on the same workpiece at an average of 0.8 s per screw, suiting mass-production stations with a stable cycle time.
Lines requiring full data traceability
Tightening result graphs and complete data records can be output, and Industrial IoT connectivity can be tailored to each company's requirements.
Frequently Asked Questions
Is the PRO-Z DK a complete automatic screw tightening machine, or do I need to build my own mechanism?
The PRO-Z DK is the part of an automatic screw tightening machine that does the tightening: it integrates the tightening spindle and Z-axis feed into one module and does not include the machine enclosure, fixtures or positioning mechanism. Positioning is handled by the host mechanism: the module can be integrated into a robot arm, XY Table or custom automation platform via TCP commands from a Robot Controller, and paired with a screw feeder as the screw supply as needed. If your line already has a robot arm or XY Table, you usually do not need to buy a complete machine; adding the tightening module and a screw feeder is enough to build an automatic tightening station. If you are planning a complete machine from scratch, an equipment integrator typically designs the mechanism and then mounts this module. Pre-installation evaluation and mechanism integration advice are provided by Utrun-Tech in Taiwan.
How is the PRO-Z different from a conventional automatic screw tightening machine?
A conventional automatic screw tightening machine controls the torque and speed of the rotating spindle, while the vertical direction is usually just a constant-speed pressing mechanism. The patented PRO-Z technology brings the motion speed and pressure of the vertical Z axis into synchronized control, matched to the tightening action: after the user enters the screw specification, motion parameters and conditions, the system can control variables that are impossible or difficult to manage in conventional tightening. In testing with M0.8 screws on the same workpiece, it performed more than 1200 consecutive tightening and loosening cycles, averaging 0.8 s/screw.
Can the PRO-Z DK be integrated with a robot arm or XY Table?
Yes. The module is controlled via TCP commands from a Robot Controller and can be integrated into a robot arm, XY Table or custom automation platform. System requirements for the Pro-Z Master control software are a 1.6GHz dual-core processor (or higher), 2GB RAM (or higher), 20MB of program space, LAN × 2 (only 1 needed when used with a network switch), USB 2.0 × 1, Windows 7 Home Service Pack 1 (or later) and .NET Framework 4.8 (or later).
Which electric screwdriver specifications are available on the PRO-Z DK module?
There are five types: S type, target torque 10~45 mN·m (0.1~0.45 kgf·cm), approx. 280g; L type, 50~180 mN·m (0.5~1.836 kgf·cm), approx. 405g; XL type, 200~700 mN·m (2.0~7.14 kgf·cm), approx. 1000g; these three have a maximum speed of 800rpm and a DC24V/3A power supply. GM type, 600~1500 mN·m (6.12~15.3 kgf·cm), approx. 1100g, and GX type, 1700~3200 mN·m (17.34~32.64 kgf·cm), approx. 1410g; these two have a maximum speed of 400rpm and a DC48V/3A power supply. Overall applicable screw sizes are M0.6~M5.
What are the Z-axis stroke and specifications of the PRO-Z DK?
The compact electric cylinder in the module has a stroke of 30mm (effective thread length), weighs 600g and uses a DC24V/3A power supply. During tightening, the Z-axis motion speed and pressure can be controlled in sync with the rotation, and the module can output tightening result charts and complete data traceability records; Industrial IoT connectivity solutions can also be customized to company requirements.
