Fastening & Torque Solutions

Preston integrates fastening technologies including ASG, Sumake and Tohnichi, with the suitable brand and tool selected according to the application requirements.

Selection depends on the joint requirement, screw type, torque requirement, operator workflow, quality-control needs and required production data. Preston can evaluate the application and recommend a suitable solution.

A conventional tool mainly performs the tightening operation. A smart fastening system can also control and verify the process using functions such as torque or angle monitoring, tightening limits, OK/NG judgement, screw count and sequence control.

Torque indicates the tightening resistance, while angle shows how far the fastener rotates. Monitoring both gives a clearer picture of whether the joint was tightened as expected.

Yes. Depending on the system, fastening can include pass/fail verification, screw-count and sequence control, tightening-data capture and integration with torque arms, screw feeders, fixtures and production workstations.
