Precision manual screwdriver Wiha 42482, Single, length 150 mm

The Wiha 42482 Single precision manual screwdriver is a compact hand tool with an overall length of 150 mm designed for accurate screwdriving in electronics, precision mechanics and small assembly tasks. Its slim profile and fine tip alignment provide controlled torque transfer and precise engagement with small fasteners. The screwdriver is intended for tasks where delicate components require careful handling and repeatable screwdriving performance.

Advantages

The tool combines a short 150 mm length with a precision-machined tip to minimize wobble and increase contact accuracy on fine screws. The ergonomic handle geometry allows for stable fingertip control and measured torque application, reducing the risk of over-tightening. The robust shaft construction ensures straightness and durability while enabling reliable alignment in recessed or confined work areas.

How to use

Select the screwdriver and verify the tip matches the screw head to ensure full contact. Position the tip squarely in the screw recess, apply light axial pressure and turn using controlled finger or wrist motion to drive the screw. For removal, reverse the turning direction while keeping the tip aligned to avoid cam-out. Use short, steady rotations when working with delicate components and stop once the desired seating or preload is reached.

Recommendations

Inspect the tip before use and replace the tool if the tip shows wear or deformation. Work on energized equipment only when power is safely isolated. For repeatable torque control on critical assemblies, consider using a calibrated torque tool designed for the required torque range. Store the screwdriver in a protective holder to preserve tip geometry and avoid contamination of sensitive components.
