Gearwrench 89624 Torque Limiting Screwdriver 1/4 in

Product Description

The GEARWRENCH 89624 is a torque limiting screwdriver with a square drive designed for precision fastening applications where consistent torque output is critical. It accepts 1/4 inch square drive bits and limits applied torque within a range of 160 to 800 inch/oz (1.129 to 5.649 Nm), preventing overtightening on sensitive fasteners. The driver disengages automatically when the set torque threshold is reached. At 1.04 pounds and compact dimensions, it is a practical bench or field tool for technicians who need repeatable results without a separate torque wrench setup.

This screwdriver is suited for light-duty precision assembly work across electronics, HVAC controls, small appliance service, and low-voltage electrical panel work. It is particularly useful when tightening terminal screws, control board mounting hardware, or other fasteners with manufacturer-specified torque limits. The square drive accepts standard 1/4 inch bit inserts, making it compatible with a wide range of Phillips, slotted, Torx, and square bit tips already in a technician's kit.

Key Features

• Torque range of 160 to 800 inch/oz (1.129 to 5.649 Nm) for precision fastening control
• 1/4 inch square drive accepts standard interchangeable bit inserts
• Automatic torque limiting mechanism prevents overtightening
• Compact build at 7.68 inches in length for use in tight spaces
• Lightweight at 1.04 pounds for reduced hand fatigue during repetitive tasks

Compatibility

Designed for use with standard 1/4 inch square drive bit inserts. Compatible across applications requiring controlled fastener torque in the 160 to 800 inch/oz range.

Installation Notes

This tool is used by HVAC technicians, electricians, and electronics service professionals for low-torque fastening tasks. Before servicing any control board or electrical component, de-energize the equipment and verify power is off at the disconnect or breaker. Select the appropriate 1/4 inch bit insert for the fastener type before applying torque. Do not use this tool to back out heavily corroded or seized fasteners, as reverse loading may affect the torque limiting mechanism.
