Wiha 66996 Ball End Hex Key Set 1.5 to 10mm 9 Piece

Product Description

The WIHA 66996 is a 9-piece L-key ball end hex key set covering metric sizes from 1.5 to 10mm. Each key features a ball end tip that allows angled entry up to 30 degrees, enabling fastener access in tight or obstructed spaces without requiring a straight-on approach. The keys are constructed from steel for durability under the torque demands of routine mechanical and equipment maintenance work. This set is suited for HVAC technicians, electricians, plumbers, and other trade professionals who regularly work with hex socket fasteners on equipment panels, motors, and assemblies.

This set is appropriate for use in residential and commercial service environments where metric hex fasteners are common. Typical applications include tightening or loosening set screws on motor shafts, adjusting equipment panels, and servicing mechanical assemblies that require metric L-keys. The ball end design reduces repositioning time when working in confined areas around installed equipment.

Key Features

• Ball end tip allows angled fastener engagement in confined spaces
• 9 metric sizes included: 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10mm
• Steel construction for strength and resistance to rounding under torque
• L-key form factor provides leverage for both driving and fine adjustment
• Set packaging keeps all nine keys organized on a single holder

Compatibility

Designed for use with standard metric hex socket fasteners. Covers the 1.5 to 10mm hex size range common in HVAC equipment, electrical enclosures, and mechanical assemblies.

Installation Notes

Use is limited to manual torque applications. Power-down or de-energize equipment before servicing fasteners on electrical or HVAC components. Select the correctly sized key before applying force to avoid rounding the fastener socket. Inspect keys periodically for wear or deformation and replace any damaged key before continued use.
