Sequence
Operators skip intermediate passes or tighten in the wrong order, especially under takt pressure.
Applications · Tightening
Every fastener in the right place, in the right order, at the right torque.
Arkite connects to smart tools and controls when and where they may run. The next step is released only when the specified torque is confirmed, and each value is stored with the unit.

The operation
Critical joints, invisible errors
Many assemblies depend on the correct tightening of screws, nuts and bolts. Joints often require a fixed sequence, several torque programs on one product or multiple passes from low to high torque.
A missing screw, a skipped pass or the wrong program is rarely visible on the finished product. It is often only found in the field, where the cost is highest.
Typical challenges
What smart tools alone do not solve
Location
A tool reports a correct torque, but not whether it was applied to the correct fastener.
Program selection
Products with several torque values depend on the operator choosing the right program each time.
How Arkite works here
Tightening as a controlled workflow
- 01
Connect the tool
Smart tools connect over Open Protocol, Ethernet or Modbus. No programming is required to configure the communication module.
- 02
Indicate the fastener
The projector marks the next screw or bolt position on the product, following the defined sequence.
- 03
Select program and enable
Arkite selects the required program or torque automatically and enables the tool only during the correct step. With VALIDATE, it is enabled only at the correct location on the workbench.
- 04
Confirm the torque
The next step is blocked until the specified torque is confirmed. Deviations can follow a defined rework or scrap path.
- 05
Validate small parts
Nuts and screws are validated by combining the pick from the correct bin, the tool position and the torque result.
Controlled tightening.
Video placeholder Operator at a VALIDATE workstation with a smart tightening tool, 30 to 45 seconds: the tool is enabled only when it is at the projected location, the program is selected automatically, the torque result is confirmed on the screen, the next step unlocks, and the torque value appears in the unit log. Tool branding kept discreet.

Data captured
A torque record for every unit
- Torque values per fastener and per assembled unit
- Program used and step in which it was applied
- Sequence deviations and tightening errors
- Step durations for each tightening operation
- Operator, time and serial number
- Rework or scrap decisions taken at the station
