Wiha easyTorque Adaptor 4.0Nm for slimBits & slimVario

The Wiha easyTorque Adaptor is designed for controlled screw tightening, promoting safe work practices in electrical applications. This innovative tool guarantees process-safe use, safeguarding against material damage and eliminating the need for costly refinishing work. Its precision ensures that every fastener is secured with the exact amount of force required, protecting both the screw and the workpiece.

Fully compatible with the entire Wiha slimBit system, this insulated torque adaptor also provides a secure hold for 75mm slimBits. It effortlessly transforms compatible Wiha screwdrivers—including the slimVario with bit holder, the slimVario Stubby electric, and the LiftUp electric screwdriver with bit magazine—into a dedicated, accurate torque tool in moments. This versatility makes it an essential addition to any professional electrician's or technician's toolkit.

Operation is intuitive and reliable. When the preset torque of 4.0Nm is reached, a clear audible click signal is heard, and the visual indicator—a yellow ring and red adaptor—can be seen rotating in opposite directions. This dual feedback system provides absolute confidence that the correct torque has been applied. With a release accuracy of ±10%, the tool complies with the stringent requirements of EN ISO 6789, ensuring professional-grade results every time.

Applying the correct torque is critical; it prevents stripping thread heads, overtightening, and material stress, meaning no follow-up work or repairs are necessary. Each easyTorque adaptor is individually tested at 10,000 V AC and officially approved for safe use in environments up to 1,000 V AC, offering peace of mind when working on live electrical components. Its compact and robust design is built for durability and daily use in demanding professional settings.
