STAHLWILLE Calibrated Torque Screwdriver, 4 To 10 Nm, 1/4 in Drive

This torque screwdriver is a calibrated tool designed for controlled fastening in industrial assembly and maintenance environments. It delivers adjustable torque in a mid-range span and meets a recognised international calibration standard, making it suitable for tasks where precise torque application is required. The tool incorporates a small drive Interface and a Compact profile to fit into confined workspaces common in automation, electronics and mechanical settings.

• Torque adjustment range 4–10 Nm for consistent clamp force
• 1/4in drive for compatibility with common bits
• Calibrated to DIN EN ISO 6789-2:2017 for traceable accuracy
• Overall length 235mm for access into tight assemblies
• Subtype calibrated for repeatable torque delivery

• Suitable for assembly of electrical control panels requiring set torque
• Ideal for tightening fasteners on electronic enclosures
• Used for repetitive mechanical assembly with specific torque needs
• Can be used in automation equipment maintenance where precision is required

It uses a 1/4in drive, enabling the use of a wide range of hex and screwdriver bits common in industrial kits.

Calibration is performed to DIN EN ISO 6789-2:2017, providing documented traceability for torque settings.

It is specified as non-ESD, so separate ESD precautions or alternative tools are required for sensitive components.

The adjustable range of 4–10 Nm accommodates many fasteners found in electronics and light mechanical assemblies.
