Wera 05022070001 Long Arm Hex Key 3mm

Product Description

The WERA 05022070001 is a long arm L-handle hex key designed for fastening and loosening hex socket screws in tight or recessed positions. The long arm extends reach and allows high-torque application on the short arm side, while the L-handle configuration gives the technician a comfortable grip for rapid rotation or precise torque control. With a 3 mm hex size and an overall length of 112 mm, this key suits detailed mechanical assembly, HVAC equipment panels, electrical enclosures, and general trade service work. Licensed tradespeople and skilled technicians who work with metric hex fasteners will find this a standard addition to a field tool kit.

This hex key is suited for residential and commercial service applications where metric hex socket fasteners are common. Typical use cases include HVAC equipment access panels, motor mounts, electrical enclosures, plumbing fixture hardware, and general mechanical assembly. The long arm style improves access in confined spaces where a standard-length key cannot seat fully into the fastener head.

Key Features

• Long arm style extends reach into recessed or confined fastener locations
• L-handle design allows high-torque drive on one end and rapid spin on the other
• 3 mm hex size fits metric hex socket fasteners commonly found in trade equipment
• 112 mm overall length falls in the 4 to 6.9 inch range for compact carry
• Lightweight at 0.015 pounds for easy inclusion in a field tool pouch

Compatibility

Designed for use with M3 metric hex socket screws and bolts across HVAC, electrical, and mechanical service applications.

Installation Notes

This tool is used by HVAC technicians, electricians, plumbers, and general mechanical service professionals. Always de-energize equipment and follow applicable lockout/tagout procedures before opening panels or accessing fasteners near live components. Inspect the hex key tip for wear or rounding before use, as a damaged tip can strip fastener heads. Apply steady, controlled force through the L-handle to avoid cam-out on precision fasteners.
