Wiha 28522 Adjustable Torque Screwdriver 15-80 In/oz

Product Description

The WIHA 28522 is an adjustable torque screwdriver with a 1/4 inch drive, designed for precision fastening applications where controlled torque output is critical. It covers a torque range of 15 to 80 inch-ounces (in/oz), with a calibration accuracy of plus or minus 10 percent. The tool is ESD safe, making it suitable for use around sensitive electronic components where electrostatic discharge is a concern. The ergonomic handle reduces hand fatigue during repetitive use. Licensed electricians, electronics technicians, and equipment service professionals are the primary installers of this tool.

The WIHA 28522 is used in residential, commercial, and industrial settings where consistent, repeatable torque application is required. Common applications include electrical panel work, electronics assembly, instrumentation calibration, and precision equipment service. Its ESD-safe construction makes it especially appropriate for environments with sensitive circuit boards, control modules, or low-voltage electronics. The 1/4 inch drive accepts standard bits, allowing for flexibility across a wide range of fastener types and sizes.
