Wiha 29209 Pre-set Torque Screwdriver 8 In/lb

Product Description

The WIHA 29209 is a pre-set torque screwdriver rated at a fixed 8 inch-pounds (0.90 Nm) of torque, designed for applications where consistent, repeatable fastening force is critical. It features a 1/4 inch drive and a cushion grip handle for controlled hand torque on sensitive assemblies. At 130 mm (approximately 5.1 inches) overall length and weighing 0.38 pounds, it is compact enough for confined-space work. Accuracy is rated at plus or minus 10 percent, and the tool is rated for a minimum of 5,000 cycles. Licensed electricians, HVAC technicians, and instrumentation installers use pre-set torque screwdrivers where over-torquing terminals or fasteners would damage components.

This screwdriver is suited for low-torque fastening tasks in electrical panel work, control board terminal connections, and precision mechanical assemblies. The pre-set design eliminates the need for field adjustment, making it appropriate for production-line, service-bench, or field-service environments where a single fixed torque value is required. The cushion grip handle reduces hand fatigue during repetitive use. It is not tether capable and is intended for standard bench or hand-carry use.

Installation Notes

This tool is installed into service by electricians, HVAC technicians, and mechanical technicians for terminal and fastener torquing tasks. Always power down and de-energize equipment before torquing electrical terminals. Do not attempt to override or modify the pre-set torque mechanism. Store in a protective case or toolbox to maintain calibration integrity.
