Wiha 28552 Adjustable Torque Screwdriver 0.5-2 Nm

Product Description

The WIHA 28552 is an adjustable torque screwdriver designed for precision fastening applications where controlled torque output is critical. It covers a torque range of 0.5 to 2 Nm with a graduation of 0.10 Nm per increment, allowing technicians to dial in exact settings for sensitive assemblies. The 1/4 inch drive accepts standard bits, and the cushion grip handle provides comfort during repetitive use. Accuracy is rated at plus or minus 6 percent, meeting ASME B107.14M, BS EN 26789, and EN ISO 6789 standards. Licensed electricians, HVAC technicians, and instrumentation pros rely on this tool where over-torquing would damage terminals, panels, or delicate fasteners.

This screwdriver is suited for low-torque assembly and service work in residential and light commercial environments. Typical applications include tightening terminal screws on control boards, low-voltage wiring connections, panel components, and instrumentation hardware. The included calibration certificate supports quality-control documentation requirements on job sites or in service shops that maintain calibration records. Rated for a minimum of 5,000 cycles, it holds up under regular production or field service use.

Compatibility

Designed for use with standard 1/4 inch drive screwdriver bits for low-torque fastening tasks in electrical, HVAC, and instrumentation service applications.

Installation Notes

De-energize all circuits and follow applicable NEC guidelines before tightening terminal or panel fasteners. Set the desired torque value using the included adjustment tool before applying the driver to any fastener. Do not use this tool to apply torques outside its rated 0.5 to 2 Nm range, as accuracy and internal mechanisms are calibrated for that window. Periodic re-calibration is recommended per your shop or job-site quality program.
