Wera 05022087001 Metric Ball End Hex Key Set 1.5-10mm

Product Description

The WERA 05022087001 is a 9-piece metric hex key set featuring long-arm geometry and a ball-end tip on each key. The long arm provides extended reach into recessed fasteners, while the ball end allows angled engagement up to 25 degrees off-axis - useful when working in tight or obstructed spaces. The set covers nine metric sizes from 1.5 mm through 10 mm, making it suited for a wide range of fastener applications across HVAC equipment panels, electrical enclosures, pump assemblies, and other trade hardware. HVAC technicians, plumbers, and electricians routinely carry a set like this for service calls where hex socket fasteners are common.

This set is intended for professional use in residential and light commercial service environments. Applications include tightening or loosening hex socket cap screws on motor mounts, blower assemblies, valve bodies, access panels, and conduit fittings. The 9-key range - 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 mm - covers the metric hex fastener sizes most commonly encountered in manufactured equipment. The long-arm configuration increases torque leverage compared to standard-arm sets, reducing hand fatigue on higher-torque fasteners.

Key Features

• Ball-end tip allows up to off-axis engagement in tight or obstructed fastener locations
• Long-arm design increases torque leverage over standard-arm keys
• 9-piece set covers 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 mm metric sizes
• Suitable for hex socket fasteners on HVAC, plumbing, and electrical equipment
• Compact set weight of approximately 0.91 pounds for portable tool kits

Compatibility

Designed for use with metric hex socket fasteners in the 1.5 mm to 10 mm range, as commonly found on manufactured HVAC equipment, pump assemblies, electrical enclosures, and other trade hardware.

Installation Notes

Use the long straight end for high-torque applications and the ball end for angled access where the straight end cannot seat fully. Do not use the ball end as the primary drive when maximum torque is required, as off-axis loading reduces effective drive engagement. Always select the correct key size to avoid fastener rounding. Store in the provided holder to maintain the set and prevent jobsite loss.
