Wera 05027102001 Hex Key Long Arm 2 Mm

Product Description

The WERA 05027102001 is a metric long-arm hex key designed for fastening and loosening hex socket screws in tight or recessed spaces. Built in an L-handle configuration, it provides two distinct drive options: the short arm for high torque and the long arm for extended reach and faster rotation. The 2 mm hex tip fits small-diameter socket head cap screws commonly found in precision assemblies, electronics enclosures, and light mechanical equipment. At 100 mm overall length, this key offers a compact profile without sacrificing leverage on the long-arm side. Weighing 0.018 pounds, it is a lightweight addition to any service pouch or tool kit.

This hex key is suited for use in HVAC equipment panels, electrical enclosures, plumbing fixture assemblies, and general mechanical maintenance where small metric fasteners are standard. The long-arm style is especially useful when clearance is limited and a straight-on drive angle is not possible. Technicians who work on commercial equipment, control panels, or precision components with M2-range fasteners will find this key a practical hand tool for daily service work.

Key Features

• 2 mm hex tip sized for small metric socket head cap screws
• Long-arm design extends reach into recessed or obstructed fastener locations
• L-handle configuration allows both high-torque short-arm and rapid long-arm driving
• 100 mm overall length keeps the profile compact for use in confined spaces
• Metric measurement system for compatibility with metric fastener standards

Compatibility

Designed as a standard metric long-arm hex key for use with 2 mm hex socket fasteners across a wide range of light mechanical, electrical, and HVAC service applications.

Installation Notes

This tool is used by HVAC technicians, electricians, plumbers, and general mechanical service professionals. Before using, confirm the fastener is a 2 mm hex drive to avoid rounding the socket. Apply steady, controlled force through the short arm when breaking loose seized fasteners, and switch to the long arm for faster run-down once the fastener is free. Do not use extension pipes or excessive force on the long arm, as this can damage small fasteners or the tool tip.
