Wera 05027108001 Hex Key 8 Mm Long Arm

Product Description

The WERA 05027108001 is a metric L-handle hex key designed for fastener-driving applications requiring extended reach and increased torque leverage. Built around an 8 mm hex end, the long-arm configuration extends the working end to provide greater access depth into recessed fasteners and confined assemblies. The overall length measures 200 mm, placing it in the 7 to 9.9 inch overall length range. This tool suits mechanics, millwrights, HVAC technicians, and industrial maintenance professionals who work with metric socket-head cap screws and set screws on a regular basis.

This hex key is suited for metric fastener work in both residential equipment and light commercial or industrial settings. The long-arm style is especially useful when driving fasteners seated deep in housings, motor mounts, or panel assemblies where a standard short-arm key cannot reach or generate sufficient torque. It is a single-piece hand tool requiring no additional hardware or installation.

Key Features

• 8 mm hex end fits metric socket-head cap screws and set screws
• Long-arm design increases torque leverage and reach into deep-set fasteners
• L-handle configuration provides two driving options: torque on the short arm, access on the long arm
• 200 mm overall length supports use in confined or deep fastener locations
• Metric sizing for use on metric-fastened assemblies and equipment

Compatibility

Designed for use with standard metric 8 mm hex-drive fasteners including socket-head cap screws and set screws commonly found in mechanical, HVAC, and industrial equipment assemblies.

Installation Notes

This is a hand tool used to drive or loosen hex fasteners and requires no installation. Always ensure the hex end fully seats into the fastener socket before applying torque to prevent rounding. De-energize or lock out equipment before servicing any fastener on powered machinery per applicable OSHA lockout/tagout procedures. Inspect the tool for wear or deformation before use.
