Wera 05074717001 Preset Torque Screwdriver 3-6 Nm

Product Description

The WERA 05074717001 is a preset torque screwdriver designed for fastening applications that require controlled, repeatable torque output. The tool is factory-set and non-adjustable, delivering torque within a fixed range of 3 to 6 newton-meters (Nm) through a 1/4 inch hex drive. At 150 millimeters in overall length and 0.3 pounds, it is a compact hand tool suited for electronics assembly, instrumentation work, HVAC controls, and other precision mechanical tasks where overtorque damage is a real concern. The preset design eliminates the need for on-the-spot calibration, making it reliable for production and service environments where consistency matters.

This screwdriver is intended for light-duty precision fastening in residential and commercial service work. The 3 to 6 Nm torque range targets small fasteners found in control panels, terminal enclosures, circuit board mounting, and similar low-torque applications. It is commonly used by HVAC technicians, electricians, and instrumentation technicians during panel assembly or equipment commissioning where manufacturer-specified torque limits must be respected. The 1/4 inch hex drive accepts standard insert bits, expanding its versatility across fastener types.

Installation Notes

This tool is intended for use by qualified technicians familiar with torque-sensitive fastening procedures. Before use, confirm the preset torque value is appropriate for the fastener and assembly specification - do not attempt to modify or override the preset mechanism. Keep the drive and bit interface clean and free of debris to ensure accurate torque transfer. Store the tool in a protective case when not in use to preserve calibration integrity.
