Wiha 28502 TorqueVario-S Precision Torque Screwdriver (5–10 In-Lbs)
The Wiha 28502 TorqueVario-S is an industrial-grade precision torque screwdriver designed to ensure consistent and accurate tightening for sensitive assembly and repair applications. Operating within a designated 5 to 10 in-lbs torque range, this driver safeguards delicate equipment interfaces and connections from over-tightening damage.
Engineered for high reliability, the TorqueVario-S features an integrated window scale that provides an unmistakable visual read of the exact torque setting, effectively eliminating false readings. To maintain precise calibration on the job site, the torque level can only be changed using the included adjustment tool, which prevents unintentional alterations during regular handling. Once the target torque setting is achieved, the tool mechanism signals the operator with a distinct audible and perceptible click.
