Product Description

The WIHA 32294 is a 7-piece fractional nut driver set built for trade professionals who need a reliable, full-range set for electrical, HVAC, and plumbing service work. The set covers six fractional sizes from 3/16 inch through 1/2 inch, with an additional 7/32 inch driver included for broader coverage. Each driver features a solid steel shaft that is through-hardened for wear resistance, paired with an ergonomic handle designed for comfort during extended use. At 9.25 inches in overall length, these drivers give technicians adequate reach in panel boxes, junction boxes, and equipment enclosures.

This nut driver set is suited for residential and light commercial service work including HVAC equipment installation, electrical panel work, and control board servicing. The fractional inch sizing makes it appropriate for standard hardware found in duct systems, electrical enclosures, and mechanical equipment. The included storage box keeps the set organized for van or toolbox storage. Technicians who regularly service equipment fastened with hex nuts in the 3/16 to 1/2 inch range will find the full size spread useful on a single job.
