Extended Product Information

FAQs

Can I use this for automotive work?

No, this tool is designed for micro-mechanical and fine electronics work and lacks the strength required for automotive fasteners.

Does this tool come with a magnetic tip?

The PicoFinish series generally relies on precise geometry to hold screws, but magnetizing it yourself is possible if needed.

Is the tip interchangeable?

No, this is a fixed-blade precision screwdriver for durability and stability.

How do I identify this tool among other Wiha screwdrivers?

The rotating cap features a symbol and the shaft is sized specifically for 0.8 mm slots.

Is the handle chemical resistant?

The grip is designed for standard shop environments, though it should be kept away from harsh solvents.

Troubleshooting

The tip slips out of the screw head

Verify that you are using the correct 0.8 mm size; if the screw slot is larger, use a larger screwdriver size to avoid stripping.

Rotation feels stiff

Check the rotating cap for debris or metal filings; use a clean, dry brush to clear any obstruction.

Pros and Cons

Pros

  • Excellent tactile feedback for sensitive tasks
  • Lightweight and well-balanced design
  • High-quality material construction durable for precision work
  • Easy to identify in a large tool kit
  • Ideal for delicate electronics and micro-mechanical assemblies

Cons

  • Not suitable for high-torque or heavy-duty tightening
  • The fine tip can be fragile if used with incorrect screw sizes
  • Limited availability for specialized industrial fasteners

Setup, Compatibility & Care

No specialized setup is required for the Wiha PicoFinish screwdriver; it is ready to use immediately. It is fully compatible with standard fine-mechanical slotted screws of 0.8 mm dimensions.

To ensure longevity:

  • Storage: Keep the screwdriver in a dedicated tool roll or organizer to prevent the fine 0.8 mm tip from bending.
  • Cleaning: Wipe the shaft with a lint-free cloth lightly dampened with isopropyl alcohol if it becomes contaminated with oil or residue from electronics.
  • Usage: Always ensure the tip is fully seated before applying pressure to avoid 'cam-out' or damage to the fastener slot.
