Wiha 26590 Nut Driver Set 8 Piece 2.5 to 6 Mm Metric

Product Description

The WIHA 26590 is an 8-piece metric nut driver set covering drive sizes from 2.5 mm through 6 mm. Each driver features a standard shaft and an ergonomic handle designed for reduced hand fatigue during extended use. The blades are chrome-plated steel, through-hardened for wear resistance, and sized for the metric fasteners common in HVAC equipment, electrical panels, and control enclosures. The set ships in a plastic storage box that keeps drivers organized on a service vehicle or workbench. Licensed electricians, HVAC technicians, and electrical contractors are the primary installers who reach for this set.

This set is well suited for residential and light commercial service work where metric hardware is the standard. HVAC technicians use these drivers when servicing equipment manufactured to metric specifications, including control boards, terminal blocks, sheet metal panels, and access covers. Electricians working on metric-fastened enclosures, DIN rail components, and European-standard equipment will also find the full size range useful. The included sizes are 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, and 6 mm.

Installation Notes

Nut drivers are hand tools and do not require power lockout before use on their own, but always de-energize any electrical panel or HVAC control enclosure before accessing internal fasteners. Select the correct driver size before applying torque to avoid rounding fastener flats. California Proposition 65 warning applies to this product per supplier data.
