Wera 05022073001 L-handle Long Arm Hex Key 9/64 in

Product Description

The WERA 05022073001 is an L-handle hex key with a long arm design, built for driving hex fasteners in tight or deep-access applications. The 9/64-inch hex tip fits standard socket head cap screws and set screws commonly found in mechanical assemblies, machinery, and equipment enclosures. The long arm provides extended reach and increased torque leverage compared to standard-length hex keys, while the short arm serves as the drive handle for high-torque turns. At 132 millimeters overall length and 0.033 pounds, it is a lightweight, single-piece hand tool suited for bench technicians, field service pros, and installation crews across multiple trades.

This hex key is used wherever 9/64-inch hex drive fasteners appear, including HVAC equipment panels, electrical enclosures, pump assemblies, and general mechanical maintenance. The L-handle form factor makes it practical for both initial fastener engagement and final torque application without a separate tool. It is well suited for residential and light commercial service work where a compact, durable hex key is needed for repetitive fastener tasks.

Installation Notes

This tool is used by HVAC technicians, electricians, plumbers, and general mechanical service professionals. No power source is required. Ensure the hex tip is fully seated in the fastener socket before applying torque to avoid rounding the drive recess. Inspect the tip for wear periodically, as a worn hex tip can damage fastener heads.
