Smart battery-powered torque wrenches for accurate, fast, and comfortable assembly work.
The Atlas Copco SRBHA series combines a 36 V smart battery, a high-performance motor, and built-in torque and angle sensing.
It is designed for industrial assembly work where precision, consistency, and easy handling matter in every tightening cycle.
How do I choose the right SRBHA model for my assembly line?
Step 1: Define the tightening requirement for the application.
Step 2: Match the tool model to the working range and joint access.
Step 3: Check whether the D version or HA version fits the station layout and accessory setup.
Step 4: Confirm the needed accessories and protective covers for that model.
What is the difference between the SRB81 model variants?
The models differ in tool configuration and intended setup, including D versions and HA versions.
The right choice depends on the application, access to the fastener, and the mounting accessory needed.
Does the tool come with a battery and charger?
The tool is ordered with a 36 V Li-Ion 2.6 Ah battery and an 18-36 V multicharger as separate ordering items.
A tool protective cover is included with the tool.
Which accessories are available for the SRBHA series?
Available accessories include Steel Bar, S-type, Sliding drive, and Square bracket options.
The correct accessory depends on the tool model and how it is integrated into the workstation.
What is the benefit of built-in torque and angle sensors?
Built-in sensing supports tighter control over the tightening process.
It helps maintain consistent results across cycles and supports structured production work.
How should I maintain the tool in daily use?
Keep the tool clean, use the included protective cover, and store the battery and charger according to station procedures.
If extra protection is needed, a battery protective cover is also available.
