Eklind Tool Co 64640 Power T Hex Key 4.0mm

Product Description

The EKLIND TOOL CO 64640 is a Power T-handle hex key designed for high-torque fastener driving in demanding trade and industrial applications. Built around a 4.0mm hex tip, the T-handle grip allows technicians to apply significantly more rotational force than a standard L-key, making it well suited for stubborn or heavily torqued socket head cap screws. The 6-inch arm length provides the reach needed in tight equipment bays and mechanical assemblies. At 0.55 pounds, it is a solid, hand-tool-grade driver appropriate for HVAC equipment service, mechanical contractors, and general maintenance professionals.

This hex key is used wherever 4.0mm socket head fasteners are found, including HVAC unit access panels, motor mounting hardware, refrigeration equipment, and general mechanical assemblies. The Power T configuration is particularly useful when working in confined spaces where a full wrench swing is not possible but firm torque is still required. Suitable for both shop and field use by HVAC technicians, plumbers, electricians, and millwrights.

Key Features

• 4.0mm hex tip fits standard socket head cap screws of that size
• T-handle design provides increased torque leverage compared to L-style hex keys
• 6-inch arm length for extended reach in confined spaces
• Sold individually (unit of measure: each)

Compatibility

Designed for use with 4.0mm socket head cap screws and set screws found in mechanical, HVAC, and industrial equipment assemblies.

Installation Notes

De-energize or lock out equipment before removing fasteners from electrical panels, motor mounts, or live mechanical assemblies. Ensure the hex tip is fully seated in the fastener socket before applying torque to avoid rounding the drive. Hand tools of this type require no calibration, but inspect the tip for wear or deformation before use on precision fasteners.
