Wera 05022071001 Hex Key 7/64 Inch Long Arm

Product Description

The WERA 05022071001 is a 7/64 inch hex key designed for driving internal hex fasteners in tight or recessed locations. The long arm configuration provides extended reach and increased torque leverage, while the L-handle design gives the technician a comfortable grip for both high-torque driving on the short arm and precision turning on the long arm. The chrome finish resists corrosion and wear under regular shop use. At an overall length of 119 millimeters and a weight of 0.022 pounds, this is a lightweight, single-piece hand tool suited for bench work, field service, and equipment maintenance across HVAC, electrical, and mechanical trades.

This hex key is appropriate for residential and commercial service applications wherever 7/64 inch internal hex fasteners are used. Common scenarios include tightening set screws on pulleys, motor shafts, and linkages, as well as assembling or disassembling equipment panels and mechanical components. The long arm style is particularly useful when fastener access is obstructed or when additional torque is needed without a separate driver tool. It is a standard addition to a field technician or shop mechanic tool kit.

Installation Notes

This tool is installed by hand and requires no power source or special equipment. Ensure the hex key is fully seated in the fastener socket before applying torque to avoid rounding the drive. Do not use extension pipes or cheater bars on the L-handle to force additional leverage beyond the tool design. Inspect the hex tip for wear or deformation before use on critical fasteners.
