Wera 05074712001 Adjustable Torque Screwdriver 25-55 In/lb

Product Description

The WERA 05074712001 is an adjustable torque screwdriver designed for precision fastening applications where controlled torque output is critical. It covers a torque range of 25 to 55 inch-pounds, making it suitable for work on sensitive electronic assemblies, panel components, and low-voltage control equipment. The pistol-style handle provides a stable grip for consistent torque delivery. Drive size is 1/4 inch with a hex tip interface, and overall length is 6 inches. Accuracy is rated at plus or minus 6 percent. Electricians, controls technicians, and HVAC service professionals use this tool when fastener torque must stay within a defined specification.

This screwdriver is well suited for residential and light commercial service work involving control boards, terminal blocks, and equipment panels where overtorquing can damage components. The 1/4 inch hex drive accepts standard insert bits, making it adaptable across a range of fastener types. The adjustable torque mechanism allows the technician to set the target torque before driving, reducing the risk of stripped fasteners or cracked housings. It is not tether capable, so it is appropriate for bench work and ground-level panel service rather than elevated or drop-zone environments.

Compatibility

Compatible with standard 1/4 inch hex insert bits. Designed for use in any application requiring controlled torque output in the 25 to 55 inch-pound range, including control panel assembly, electrical enclosure work, and equipment service.

Installation Notes

Set the desired torque value before beginning fastener installation. De-energize any electrical panel or control board before driving fasteners in live equipment enclosures, in accordance with applicable NFPA 70E safe work practices. Use the correct bit type and size for the fastener to prevent cam-out, which can compromise torque accuracy. Do not exceed the maximum torque setting of 55 inch-pounds, as this tool is not designed for higher-torque applications.
