Wera 05027109001 Hex Key 10 Mm Long Arm

Product Description

The WERA 05027109001 is a metric hex key designed for hex fasteners requiring a 10 mm drive. Built with an L-handle configuration and a long arm style, it provides the extended reach and leverage needed for deep-set or hard-to-access fasteners. The overall length of 219 mm (approximately 8.6 inches) places it in the 7 to 9.9 inch range, giving technicians a solid grip and mechanical advantage over standard short-arm versions. This tool is suited for mechanical assembly, equipment service, and installations where metric hex fasteners are common. It is handled by licensed tradespeople and skilled technicians across HVAC, plumbing, electrical, and industrial service work.

This hex key is intended for use with 10 mm metric hex fasteners in both residential and commercial service environments. The long arm design is particularly useful when accessing recessed fastener heads on equipment panels, compressor mounts, motor brackets, and similar assemblies. It is a single-piece, non-powered hand tool appropriate for any trade application requiring a metric hex drive in the 10 mm size.

Key Features

• 10 mm hex end for metric fastener applications
• Long arm style provides extended reach into recessed or deep-set fastener locations
• L-handle configuration delivers improved torque leverage compared to short-arm designs
• 219 mm overall length fits within the 7 to 9.9 inch overall length range
• Metric measurement system for compatibility with metric-standard hardware

Compatibility

Designed for use with 10 mm metric hex fasteners. Suitable for general mechanical service, equipment assembly, and maintenance applications where a long-arm L-handle hex key is required.

Installation Notes

This is a hand tool requiring no power source or special installation. Before servicing any equipment, power down electrical systems and follow applicable lockout/tagout procedures. Use the long arm for initial loosening and final tightening, and switch to the short arm for faster rotation where clearance allows. Do not use extension bars or pipe extensions to increase leverage beyond the tool design.
