Atlas Copco TFX Hydraulic Torque Wrenches

Atlas Copco TFX Hydraulic Torque Wrenches

Atlas Copco TFX is built for controlled tightening of large fasteners where high force and repeatable accuracy are essential.

The series includes multiple models with different working dimensions, torque ranges and weights, making it easier to match the tool to the joint and site access requirements.

Key Features

• Controlled tightening: The series is designed to apply hydraulic torque in a precise and repeatable way.
• Multiple sizes: Different models cover different working dimensions, helping match the tool to the application.
• Flexible drive selection: Each model is defined by its ratchet link hex size for a proper fit to the joint.
• Different tool weights: Powerhead weight varies by model, allowing selection based on handling needs.
• Clear ordering: Each model has its own ordering number for straightforward specification and ordering.

Frequently Asked Questions

How do I choose the right TFX model?
Step 1: Identify the required hex size for the joint.
Step 2: Check the torque range needed for the application.
Step 3: Compare the model dimensions with the access available on site.
Step 4: Select the matching ordering number.

What differs between the TFX models?
The main differences are working dimensions, torque range, hex size, and powerhead weight.
That makes it possible to match the model to the application.

What kind of jobs is the series suited for?
It is suited for assembly and maintenance work that requires controlled hydraulic tightening of large joints.

Do the models use different working connections?
Yes.
The model list includes connection types such as Co-Axial / Twin, along with separate ordering numbers.

How can I confirm whether a model fits my joint size?
Check the model’s Ratchet Link Hex Size and compare it to the joint size at the point of use.

What should I verify before ordering?
Confirm the TFX model, the ordering number, the hex size, and the torque requirement of the application.
