Wiha 32288 Nut Driver Set 9 Piece 3/16 to 5/8 Inches

Product Description

The WIHA 32288 is a 9-piece fractional nut driver set covering sizes from 3/16 inch through 5/8 inch, built for trade professionals who need a complete inch-series driver set on the job. Each driver features a through-hardened steel shaft for wear resistance and an ergonomic cushion grip handle for reduced hand fatigue during extended use. The set includes nine individual nut drivers and ships in a protective storage pouch, keeping the set organized on the truck or in the shop. Licensed electricians, HVAC technicians, and plumbers will find this set covers the most common fractional hex fastener sizes encountered in residential and light commercial service work.

This set is suited for residential and commercial service applications where fractional inch hex fasteners are standard. HVAC techs use nut drivers daily for panel screws, blower wheel fasteners, and equipment access hardware. Electricians rely on this size range for conduit fittings and device terminations. The nine included sizes — 3/16, 1/4, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, and 5/8 inch — span the full range of fasteners commonly encountered across HVAC, plumbing, and electrical trades.

Installation Notes

Nut drivers should be used only on fasteners matching the stated drive size to prevent rounding. Always de-energize electrical equipment and follow NFPA 70E safe work practices before using drivers near live components. Inspect handles and shafts before each use and remove any driver showing cracking, deformation, or shaft slippage from service.
