Wera 05022095001 Long Arm Hex Key 3/8 Inch

Product Description

The WERA 05022095001 is a long-arm L-handle hex key designed for driving hex fasteners in applications where standard-length tools lack reach or leverage. Built around a 3/8-inch hex drive, this key features a classic L-handle geometry that delivers two working positions: the short arm for high torque and the long arm for extended reach and faster rotation in open spaces. The overall length measures 212 millimeters (approximately 8.35 inches), placing it in the 7-to-9.9-inch overall length range. It is a staple tool for HVAC technicians, plumbers, electricians, and mechanical contractors working with hex-head fasteners on equipment panels, flanges, and assemblies.

This hex key is suited for both residential and commercial service environments. It excels in equipment rooms, mechanical spaces, and field installations where access to recessed or deeper-set hex fasteners is required. The long-arm configuration reduces the number of handle repositions needed during removal or installation, making it practical for repetitive fastener work on HVAC units, pump assemblies, pipe flanges, and electrical enclosures.

Key Features

• 3/8-inch hex drive fits standard hex-head fasteners in that size
• Long-arm style provides extended reach into confined or recessed spaces
• L-handle geometry offers a short-arm high-torque position and a long-arm speed position
• Overall length of approximately 8.35 inches (212 millimeters) for versatile access
• Inch-system sizing for compatibility with standard SAE fasteners

Compatibility

Designed as an L-handle hex key for use with 3/8-inch hex-drive fasteners in standard inch-measurement applications across HVAC, plumbing, electrical, and mechanical service work.

Installation Notes

Hex keys are installed and removed by hand without power tools. Always ensure the hex end is fully seated in the fastener socket before applying torque to avoid rounding the drive recess. De-energize or shut off equipment before servicing fasteners on live electrical enclosures or pressurized assemblies. Inspect the key tip for wear before use, as a damaged tip can damage fastener heads.
