Wera 05022076001 Long Arm Hex Key 3mm

Product Description

The WERA 05022076001 is a long arm L-handle hex key designed for fastener driving in tight or hard-to-reach spaces where standard-length keys fall short. The long arm extends torque reach, while the short arm provides high-torque driving when needed. At 160mm overall length with a 3mm hex tip, this key suits precision work on small fasteners across mechanical assemblies, HVAC equipment, and industrial applications. The L-handle format is a standard in trade toolkits for its simplicity and direct feel. Licensed tradespeople and service technicians add this key to their set for repetitive service calls where reliable hex drive access matters.

This hex key is suited for residential and commercial service work involving socket head cap screws, set screws, and similar hex fasteners. The 3mm size covers a wide range of small fastener applications found in HVAC blower assemblies, electrical enclosures, and mechanical equipment panels. The long arm style allows entry at an angle, which is useful when fastener clearance is limited.

Key Features

• Long arm design extends reach into recessed or obstructed fastener locations
• L-handle format delivers both high-torque and extended-reach driving from a single tool
• 3mm hex size fits common small socket head and set screw fasteners
• 160mm overall length provides leverage for controlled torque application
• Compact, lightweight build at 0.064 pounds suits hand-carry toolkits

Compatibility

Designed for use with 3mm hex socket head cap screws and set screws across general mechanical, HVAC, electrical, and industrial service applications.

Installation Notes

Use this tool to drive or loosen 3mm hex fasteners encountered during equipment service and assembly. Ensure the hex tip is fully seated in the fastener socket before applying torque to avoid rounding the drive recess. Power down or de-energize equipment before accessing internal fasteners on electrical or HVAC systems. No specialty training is required, but follow applicable NEC or equipment manufacturer guidelines when working inside energized enclosures.
