Wera 05074710001 Adjustable Torque Screwdriver 1/4 in Hex

Product Description

The WERA 05074710001 is an adjustable torque screwdriver built for precision fastening applications where controlled torque output is critical. It features a 1/4 inch hex drive and a straight handle with a 105 mm handle length and 6 inch overall length. Torque output is user-adjustable with a calibration accuracy of plus or minus 6 percent, making it suitable for repeatable assembly work on sensitive components such as electrical panels, control boards, and terminal connections. The tool is a single-piece unit weighing 0.3 pounds. It is intended for use by licensed electricians, HVAC technicians, and instrumentation professionals who require consistent fastening torque.

This torque screwdriver is suited for light-duty precision fastening in residential and commercial applications. Common install scenarios include torquing terminal screws on electrical enclosures, control boards, and low-voltage wiring connections where over-tightening can damage components. The 1/4 inch hex drive accepts standard hex bit inserts, making it versatile across multiple fastener sizes. Note that this tool is not tether capable and is not rated for use in elevated work environments that require tethered tool compliance.

Installation Notes

This tool is installed and operated by electricians, HVAC technicians, and other trades requiring controlled torque on terminal and component fasteners. De-energize all electrical circuits before using this tool on live panels or control boards in accordance with NFPA 70E lockout/tagout procedures. Set the torque value to the fastener manufacturer specification before use. Do not use this tool as a standard screwdriver or apply force beyond its rated torque range, as this may compromise calibration accuracy.
