Schroevendraaier-bithouder Wiha 2970

The Wiha 2970 screwdriver bit holder is an insulated torque adapter designed for use with LiftUp and slimVario® screwdriver sets. It converts compatible Wiha slimVario screwdrivers with bit holders, slimVario Stubby electric and LiftUp electric screwdrivers with bit magazine into a torque tool that provides controlled screw tightening up to 2.5 N·m. Individually tested to IEC 60900 and approved for live work up to 1,000 V AC, the adapter helps avoid material damage and reduces the need for rework.

Advantages

The torque adapter supplies repeatable, process-safe torque with a release accuracy of ±10%, meeting EN ISO 6789 requirements for hand torque tools. A clear tactile click and visual indication — the yellow ring and the red adapter rotating in opposite directions — signal when the preset torque is reached. Fully compatible with the Wiha slimBit system, it accepts 75 mm slimBits and is compact and lightweight for precision tasks. Each piece is individually tested at 10,000 V AC and approved for safe use on live parts up to 1,000 V AC.

How to use

Insert a compatible slimBit into the adapter and attach the adapter to the slimVario or LiftUp screwdriver drive. Set the required torque by using the adapter as part of the screwdriver assembly; tighten the fastener until you hear a click and observe the yellow ring and red adapter rotating in opposite directions, which indicate the preset torque has been reached. Do not use bit holders or blades that are not specified for the slimBit system.

Recommendations

For safe work on live parts, regularly check the insulation of the adapter and follow local safety procedures. Use the adapter only within its rated torque and voltage limits and pair it with compatible Wiha slimBits and screwdriver systems.
