Wiha 92191 51 Pc Screwdriver Set Hex Phillips Torx

Product Description

The WIHA 92191 is a 51-piece precision screwdriver set designed for technicians who work across a wide range of fastener types and sizes. The set covers five driver categories: hex, nut driver, Phillips, slotted, and Torx. Blades are manufactured from chrome-vanadium-molybdenum tool steel for durability and corrosion resistance, with precision-machined tips for exact fit on fastener heads. Handles are cadmium-free, proportioned to blade size, and molded directly onto the blade shank for a permanent bond. The chrome-plated finish adds an additional layer of corrosion protection. The set ships in a storage box and weighs 3 pounds.

This set is suited for HVAC technicians, electricians, plumbers, and instrumentation professionals who regularly encounter both inch and metric fasteners, including fine-pitch hardware common in control boards, motors, and panel assemblies. The wide Torx range from T1 through T10 and the micro hex selection starting at 0.028 inches make this set practical for precision electronic and mechanical work in residential and light commercial applications. The included storage box keeps all 51 pieces organized and accessible on the job.

Installation Notes

De-energize all electrical circuits and shut off power at the breaker or disconnect before using drivers on control boards, terminals, or panel components. Select the driver size that seats fully in the fastener recess to avoid stripping. Precision screwdrivers are intended for hand torque only — do not use with power drivers or extension bars. Store in the provided box to protect tip geometry between uses.
