Precision Nutdriver Set 8pcs Solid mm

The Wiha Tools 26590 set contains eight solid-shank nut drivers in metric sizes from 2.5 mm to 6 mm. Each driver features a non-magnetic tip and a gray finish. The shank length measures 2 7/16 in and the bolt clearance is 5/16 in. This new hand tool kit is designed for precision fastener work.

Suited for technicians needing a compact range

Professionals who require ESD-safe or insulated handles should look elsewhere because this set offers neither feature. Users who need magnetic tip retention for holding fasteners will not find it here. The absence of a holding function also limits use in deep or awkward locations where the fastener must stay on the driver.

Check that your fasteners match the metric sizes

Verify that the 5/16 in bolt clearance fits the hardware you plan to service. Confirm that a 2 7/16 in shank length reaches the nuts in your assemblies. Ensure the non-magnetic tips are acceptable for your workflow and that insulation or ESD protection is not required by your safety standards.

Questions about this item

Which metric nut sizes does the 26590 set cover so I know if my existing fasteners match?

The set includes eight solid-shank drivers sized 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm and 6 mm for metric nuts.

Will the 5/16 in bolt clearance on these drivers fit the older bolts I already have?

Yes, each driver has a 5/16 inch bolt clearance, so it slides over bolts of that diameter or smaller without binding.

How can I confirm the drivers are non-magnetic and ESD-safe as described once I start using them?

The drivers are non-magnetic by design and are not ESD-safe; test with a small steel screw — it will not cling — and note the lack of ESD markings on the handles.
