Wiha 36995 Long Arm Ball End Hex Key Set 22 Piece

Product Description

The WIHA 36995 is a 22-piece L-key hex key set featuring long arm geometry and ball end tips, designed for professional technicians who need fast, flexible fastener access in tight or angled workspaces. The ball end allows engagement at angles up to 25 degrees from the fastener axis, reducing the need to reposition in confined areas. Keys are manufactured from Chrome Vanadium Molybdenum steel, providing high torsional strength and resistance to wear. The set covers inch sizes from 0.05 to 3/8 inches and metric sizes from 1.5 mm to 10 mm, making it a dual-standard solution for HVAC, electrical, and mechanical service work.

This set is suited for residential and commercial service technicians who regularly encounter hex socket fasteners on equipment panels, motor mounts, valve assemblies, and control components. The long arm design increases torque leverage compared to standard-length keys, useful when breaking loose seized fasteners. Both inch and metric sizes are included, supporting domestic and imported equipment. Licensed HVAC technicians, electricians, plumbers, and general mechanical contractors will find this set applicable across a wide range of service calls.

Key Features

• Ball end tips allow fastener engagement at off-axis angles, improving access in restricted spaces
• Long arm design provides increased torque leverage over standard-length hex keys
• Chrome Vanadium Molybdenum steel construction for high torsional strength and durability
• 22-piece set covers inch sizes from 0.05 to 3/8 inches and metric sizes from 1.5 to 10 mm
• Dual inch and metric coverage supports domestic and imported equipment in a single set

Compatibility

Designed for use with standard hex socket fasteners in inch sizes from 0.05 to 3/8 inches and metric sizes from 1.5 to 10 mm, compatible with hex-drive applications across HVAC, plumbing, electrical, and general mechanical service equipment.

Installation Notes

Power down and de-energize all equipment before loosening or tightening fasteners on electrical or mechanical components. Always select the correct key size for a snug fit in the fastener socket to prevent rounding. The long arm should be used for torque application and the short arm for high-speed driving in open areas. Inspect keys regularly for wear or deformation and replace any that show signs of damage before use.
