Wera 05022072001 Long Arm Hex Key 1.00 Mm L-handle

Product Description

The WERA 05022072001 is a long-arm hex key designed for fastening and loosening hex socket fasteners in tight or recessed locations. Built with an L-Handle configuration, it delivers two distinct torque options from a single tool: the short arm provides high torque for breaking loose stubborn fasteners, while the long arm allows extended reach and faster rotation at lower torque. The 1.00 mm hex tip engages small-profile socket head screws with precision. Overall length is 126 mm (approximately 4.96 inches). Weighing just 0.026 pounds, it is lightweight enough for repeated use in confined spaces. Trade professionals in HVAC, plumbing, and electrical work routinely rely on hex keys at this size for equipment panel fasteners and instrument hardware.

This hex key suits residential and light commercial applications where small hex socket fasteners are common. Typical install scenarios include tightening set screws on shafts, couplings, and valve packing glands, as well as accessing recessed fasteners inside control panels or mechanical enclosures. The long-arm design reduces wrist fatigue during repetitive fastener driving. It is appropriate for bench work, field service calls, and equipment commissioning where a 1.00 mm hex drive is required.

Key Features

• Long-arm style extends reach into recessed fastener locations
• L-Handle design provides both high-torque short-arm and fast-rotation long-arm options
• 1.00 mm hex tip for small socket head screws and set screws
• 126 mm (approximately 4.96 inches) overall length falls in the 4 to 6.9 inch range for compact portability
• Lightweight at 0.026 pounds for reduced hand fatigue during extended use

Compatibility

Designed for use with 1.00 mm hex socket fasteners including socket head cap screws, set screws, and similar hex drive hardware found in mechanical, HVAC, and electrical equipment.

Installation Notes

Hex keys are hand tools requiring no power source and are typically used by HVAC technicians, plumbers, electricians, and mechanical service professionals. Always de-energize electrical equipment and shut off fluid systems before accessing internal fasteners. Inspect the hex tip for rounding or wear before applying torque to avoid stripping fastener sockets. Apply steady, controlled force to prevent tool slippage on small-profile hex fasteners.
