FAQs

Is this screwdriver magnetic?

This model features a standard steel tip and is not specifically advertised as magnetic.

Can I use this for electrical work?

No, this is a standard mechanical screwdriver and is not insulated for electrical safety. Do not use on live circuits.

What is the difference between this and the T20 version?

The main difference is the tip geometry; the T25 is larger than the T20 and will not fit in smaller Torx fasteners.

Does the handle hold up against harsh chemicals?

The MicroFinish handle is designed for industrial use and is resistant to most common shop chemicals and oils.

Can I use a hammer on the end of the handle?

No, this tool is not designed to be used as a striking tool.

What should I do if the handle becomes damaged?

If the handle grip is compromised, it is recommended to replace the tool to ensure safety and maintain the intended torque control.

Troubleshooting

Screwdriver slipping out of the screw head

Ensure you are using the correct T25 size and that the fastener head is free of debris; if the screw head is already stripped, use a screw extractor instead.

Handle surface becomes slick

Clean the handle with a degreaser and a cloth to restore the friction properties of the MicroFinish material.

Tip bending under pressure

Ensure you are applying force directly along the axis of the screw; avoid side-loading or prying motions which exceed the tool's torque capacity.

Pros and Cons

Pros

  • Excellent grip performance in slick, oily conditions
  • High-quality steel construction resists bending and wear
  • Precise fit reduces risk of damaging delicate fasteners
  • Well-balanced design for comfortable extended use

Cons

  • Fixed blade design is not compatible with interchangeable bits
  • Specifically limited to T25 Torx heads
  • Not intended for electrical work as it is not VDE certified

Setup, Compatibility & Care

This screwdriver is a ready-to-use tool requiring no assembly or complex setup. It is fully compatible with any standard T25 Torx socket or head.

To ensure the longevity of your Wiha tool:

  • Cleaning: Wipe the shaft and handle with a clean, dry cloth after exposure to oils or chemicals to maintain the integrity of the MicroFinish texture.
  • Storage: Store in a dry tool chest or rack. Avoid using the screwdriver as a pry bar, chisel, or punch, as this can snap the hardened steel tip.
  • Inspection: Regularly check the T25 tip for signs of rounding or fatigue; if the tip shows wear, replace it to prevent damage to expensive equipment fasteners.
