Wera 05022068001 Long Arm Hex Key 5mm

Product Description

The WERA 05022068001 is a long arm L-handle hex key designed for driving hex socket fasteners in tight or recessed locations where a standard-length key lacks reach or leverage. The long arm extends to 100 millimeters overall length, giving technicians and tradespeople a mechanical advantage when seating or breaking loose stubborn fasteners. The 5mm hex tip fits the corresponding socket head cap screws and set screws common across HVAC equipment panels, electrical enclosures, plumbing fixtures, and light mechanical assemblies. The L-handle configuration allows high-torque driving on the short arm and rapid spin-down on the long arm.

This hex key is suited for residential and light commercial service work where 5mm hex fasteners appear on equipment covers, access panels, pump housings, and mounting hardware. It is a single-piece hand tool appropriate for HVAC technicians, electricians, plumbers, and general trade use. The compact package weight of 0.029 pounds makes it easy to carry in a service bag or pouch alongside other hand tools.

Key Features

• Long arm style at 100 millimeters overall length for extended reach into recessed fasteners
• 5mm hex drive size fits standard metric hex socket fasteners
• L-handle design allows torque application on the short arm and quick rotation on the long arm

Compatibility

Designed for use with 5mm hex socket fasteners across a wide range of residential and commercial trade equipment and mechanical assemblies.

Installation Notes

Insert the hex tip fully into the fastener socket before applying torque to avoid rounding the drive surfaces. Use the short arm for high-torque applications and the long arm for faster spin-down once the fastener is seated. Ensure power is removed from any electrical equipment before accessing fastened covers or panels. This tool requires no special certifications to use but should be applied within the scope of the applicable trade license for the task at hand.
