Wiha 29211 Torque Screwdriver 155 In/oz 5/32 Inch Drive

Product Description

The WIHA 29211 is a pre-set torque screwdriver designed for precise, repeatable fastening in electrical, electronics, and instrumentation work. It is factory-set to a fixed torque value of 155.2 inch-ounces (1.100 Nm) and cannot be adjusted in the field, which eliminates operator error on critical fastener torque requirements. The 5/32-inch drive accepts standard bits for hex or slotted applications. A cushion grip handle reduces hand fatigue during extended use. Accuracy is rated at plus or minus 10 percent, meeting ASME B107.14M, BS EN 26789, and EN ISO 6789 standards. Licensed electricians, instrumentation techs, and panel builders are the primary installers.

This screwdriver is suited for light-duty fastening applications where consistent, pre-defined torque is required — such as terminal block screws, panel components, and low-voltage electrical connections. The pre-set design is common in environments where over-torquing sensitive components is a risk. The tool is rated for a minimum of 5,000 cycles, making it appropriate for repetitive production or service work. At 7.5 inches in overall length and 0.25 pounds, it fits easily in a standard tool pouch.

Compatibility

Designed as a pre-set torque screwdriver for electrical panel assembly, instrumentation, and low-voltage fastening applications requiring a fixed 155.2 inch-ounce torque setting with a 5/32-inch drive.

Installation Notes

This tool is intended for use by licensed electricians, instrumentation technicians, and assembly professionals. De-energize all circuits and follow applicable NEC requirements before fastening terminal or panel components. Do not attempt to modify or override the pre-set torque mechanism. Inspect the tool periodically to confirm torque output remains within the rated accuracy tolerance.
