Impact wrench Hazet 9012ATT 1/2 inch drive — loosening torque 550 Nm

Hazet 9012ATT 1/2" drive impact wrench is a handheld pneumatic/electric tool engineered to provide a loosening torque of 550 Nm for demanding workshop and automotive applications. Designed to apply controlled impact force, the tool helps release tight, rusted or seized nuts and bolts while reducing manual effort and improving workflow efficiency during repair and maintenance tasks.

Advantages

The impact wrench delivers a clear specification of loosening torque at 550 Nm, combining high output with a compact 1/2" drive interface compatible with standard sockets. Its impact action reduces vibration transmitted to the operator compared with manual breaker bars, and the tool’s design focuses on repeatable performance for routine service work. The 1/2" drive size balances torque capacity and access in confined spaces commonly encountered in vehicle and machine maintenance.

Suitable for

• Automotive wheel and suspension fastener removal
• General workshop maintenance and repair where high torque is required
• Industrial equipment disassembly and reassembly
• Servicing agricultural and construction machinery

Key specifications

• Drive size: 1/2" (square drive)
• Specified loosening torque: 550 Nm
• Tool type: impact wrench for high-torque fastener removal
• Intended use: automotive and workshop applications
• Compatibility: fits standard 1/2" sockets and accessories

How to use

Select a correctly sized 1/2" socket and attach it securely to the impact wrench. Position the socket squarely on the fastener and apply steady contact before activating the tool. Operate the wrench in short bursts, allowing the impact mechanism to break the fastener free while maintaining control of the tool. After loosening, switch to appropriate torque-controlled tools for final removal or re-tightening as required by the application.

Recommendations

Use appropriate personal protective equipment, ensure the socket is fully seated on the fastener, and follow workshop safety practices. Verify that the wrench specification matches the task: use the Hazet 9012ATT primarily for loosening operations up to its 550 Nm rating and avoid using it as a precision tightening tool.
