Wera 05074700001 Adjustable Torque Screwdriver 1/4 in Hex

Product Description

The WERA 05074700001 is an adjustable torque screwdriver designed for precision fastening applications where controlled torque delivery is critical. It covers a torque range of 0.3 to 1.2 newton-meters (Nm) with a 0.05 Nm increment, allowing fine-tuned adjustments across the full range. The 1/4 inch hex drive accepts standard hex bits, and the straight handle measures 105 mm with an overall length of 6 inches. Accuracy is rated at plus or minus 6 percent, meeting DIN EN ISO 6789 standards. Electricians, HVAC technicians, and instrumentation specialists use this tool when fastener torque must be repeatable and verifiable.

This screwdriver is suited for light-duty precision work in residential and commercial settings. Typical applications include terminal block fastening, control board component installation, equipment panel assembly, and any fastening task requiring low-torque accuracy. The adjustable mechanism and calibrated scale make it appropriate for service calls where overtightening small terminals or delicate fasteners would cause damage or create liability.

Installation Notes

This tool is used by licensed electricians, HVAC technicians, and other trades performing precision fastening on control components and terminal connections. Set the torque value before beginning work and verify the adjustment is locked per the manufacturer procedure. Do not use this tool to apply torque beyond the 1.2 Nm maximum, as exceeding the rated range will compromise calibration accuracy. Periodic recalibration per DIN EN ISO 6789 is recommended to maintain accuracy over time.
