Wera 05022074001 Long Arm Hex Key 5mm

Product Description

The WERA 05022074001 is a long arm L-handle hex key designed for fastener-driving applications requiring extended reach and added torque leverage. The long arm configuration allows technicians to access recessed fasteners in tight spaces while the short arm serves as the primary torque driver. Built for use by HVAC technicians, electricians, plumbers, and general trade professionals, this hex key fits 5mm hex fasteners and has an overall length of 140mm (approximately 5.5 inches). Its L-handle geometry provides the ergonomic grip needed for both high-torque and fine-adjustment work on equipment panels, junction boxes, and mechanical assemblies.

This hex key is suited for residential and commercial service work where 5mm hex fasteners are common. Typical applications include equipment access panel removal, motor mounting hardware, valve packing nuts, and electrical enclosure fasteners. It is a practical addition to a service technician's hand tool set for daily field use.

Installation Notes

Installation and removal of hex fasteners should be performed by qualified trade professionals using appropriate hand tool techniques. Ensure equipment is powered down and de-energized or pressure-relieved before removing fasteners on live systems. Avoid applying excessive side load to the key shaft to prevent fastener rounding or tool damage. Use the long arm for access in tight spaces and the short arm for final torque application.
