Precision Slotted Screwdriver 4.0mm

The Wiha Tools 26040 is a precision slotted screwdriver designed for fine mechanical and electronic assembly. Its 4.0 mm tip fits standard slotted fasteners found in instruments, terminal blocks and small appliances. The blade is made from Chrome Vanadium-Molybdenum steel for hardness and wear resistance. This hand tool suits technicians and hobbyists who need accurate tip engagement.

Sustained use and tip durability

Under continuous turning force the Chrome Vanadium-Molybdenum steel blade resists deformation and rounding better than standard carbon steel. The corrosion-resistant chrome finish protects the shaft during long storage or humid environments. The non-magnetic tip avoids attracting metal swarf that could interfere with sensitive components. The tool is not insulated, so it must not be used on live electrical circuits.

Compatibility checks before ordering

Verify that the fastener slot width matches the 4.0 mm tip to prevent cam-out and damage. Confirm the application does not require an insulated or ESD-safe driver, as this model provides neither. The overall length is 6 1/2 inches, so ensure adequate access in confined assemblies. California Proposition 65 warnings apply for chemicals known to cause cancer and reproductive harm.

Questions about this item

How much force can the 4.0 mm Chrome Vanadium-Molybdenum Steel blade handle during all-day use?

The blade is made from Chrome Vanadium-Molybdenum Steel for high torque resistance and corrosion resistance, with a non-magnetic finish that reduces fastener interference during extended driving tasks.

What handle or accessory is required to use the 4.0 mm slotted tip effectively?

The screwdriver has a moulded handle integrated into the 6 1/2 in overall length, so no separate handle or accessory is needed for immediate use.

Will the non-magnetic 4.0 mm tip pick up screws left by older magnetic drivers?

The tip is non-magnetic by design, so it will not attract or hold screws left by magnetic tools, reducing the risk of accidental shorts on sensitive assemblies.
