Wera 05074842001 Preset Torque Screwdriver 1/4 in Hex

Product Description

The WERA 05074842001 is a preset torque screwdriver designed for controlled fastening applications where repeatable torque output is critical. Factory-set within a range of 1.2 to 3 Newton-meters, this driver eliminates the guesswork from torque-sensitive assembly and service work. It features a 1/4-inch hex drive and an ergonomic cushion grip handle measuring 105 millimeters in overall length. The tool is ESD safe, meeting DIN EN 61340-5-1, making it appropriate for use around electrostatic discharge-sensitive components. Electricians, electronics technicians, and precision instrumentation technicians are the primary users of this driver.

This screwdriver is suited for residential and commercial service environments where small fasteners require a consistent, low-torque application. Typical use cases include control board fastener installation, terminal block screws, enclosure covers, and other precision assembly tasks where over-torquing would damage threads or housings. The preset design means no field adjustment is needed or possible, reducing the chance of technician error during repetitive tasks.

Compatibility

Designed as a precision hand tool for use with standard 1/4-inch hex drive bits in low-torque fastening applications, particularly in ESD-sensitive service environments.

Installation Notes

This tool is intended for use by qualified technicians performing precision assembly or service work on electronic and electrical components. Always power down and de-energize equipment before fastening components near live circuits. Use only compatible 1/4-inch hex bits rated for the application. The preset torque setting is not field-adjustable and should not be disassembled or modified.
