Wiha 92190 Precision Screwdriver Set 50 Piece

Product Description

The WIHA 92190 is a 50-piece precision screwdriver set built for technicians who need a complete range of drive types in a single organized kit. The set includes 10 slotted, 10 Torx, 15 hex, 4 Phillips, and 10 nut drivers, covering the most common fastener types encountered in HVAC, electrical, and control-panel service work. Blades are manufactured from chrome-vanadium-molybdenum tool steel, hardened for wear resistance and finished with corrosion-protective chrome plating. Handles are cadmium-free plastic, proportioned to blade size, and feature rotating caps for precise torque control. The set ships in a storage box and weighs 3.67 pounds.

This set is well suited for residential and light commercial service work where a technician needs both imperial and metric drive sizes across multiple driver types. The Torx range covers T1 through T10, making it particularly useful for modern HVAC controls, circuit boards, and variable-speed drive components that use small Torx fasteners. The hex sizes span both metric and fractional inch dimensions, and Phillips sizes run from 000 to 1, supporting precision electronics and standard equipment fasteners alike. Electricians, HVAC technicians, and controls specialists will find the full size coverage practical for panel work and component replacement.

Installation Notes

Always de-energize electrical equipment and verify zero voltage with a meter before using any hand tools on live panels or control boards. HVAC technicians should follow NEC and equipment manufacturer lockout-tagout procedures before accessing wiring compartments. Inspect blade tips before use and replace any driver showing visible wear to avoid fastener damage. Store the set in its provided box to protect precision tips from contamination and mechanical damage.
