TORQUE HUB IS
MORE THAN JUST TORQUE

Track real-time torque, depth, and angle with the Torque Hub,
then export detailed screw pile reports straight from your smart device.

Data is sent over a Wi-Fi signal from the Torque Hub device (mounted between the output shaft and torque head) to a smartphone, via the app – TorqApp.

The Torque Hub and TorqApp system measures not only torque, but also screw anchor angle, rotations per minute, installation depth, geolocation, rotations during installation, and more.

Reports can be exported directly from your smart device, via email. Simply enable ‘Hotspot’ on a smartphone via TorqApp.
