Wiha 36953 Ball End Hex Key 1/8 Inch Long Arm

Product Description

The WIHA 36953 is a long-arm L-handle hex key with a 1/8 inch ball end tip, designed for fastener-driving in tight or angled spaces where direct tool access is not possible. The ball end allows engagement at off-axis angles, making it practical for confined mechanical assemblies. The L-handle configuration provides a short-arm side for high-torque seating and a long-arm side for fast, low-torque rotation. At 4.6 inches overall length and 0.02 pounds, the tool is lightweight and fits easily in a tool pouch or roll. Electricians, HVAC technicians, and equipment service professionals use this key for panel fasteners, equipment covers, and component mounting hardware.

This hex key is suited for residential and commercial service applications where 1/8 inch hex fasteners are encountered on mechanical equipment, electrical enclosures, and HVAC components. The long-arm style extends reach into recessed fastener locations and allows faster spin-down of fasteners with less wrist effort. It is a single-piece hand tool requiring no additional accessories and is sold individually.

Key Features

• Ball end tip allows up to 30-degree off-axis driving for fasteners in restricted spaces
• Long-arm configuration provides extended reach and faster rotation on low-torque passes
• L-handle design delivers leverage on the short side for final seating and breakaway
• 1/8 inch hex size covers a common fastener dimension in HVAC, electrical, and plumbing equipment
• Black handle provides visual contrast and grip identification in a tool bag
• Lightweight at 0.02 pounds for all-day carry without fatigue

Compatibility

Designed for use with standard 1/8 inch internal hex fasteners found on mechanical equipment, enclosures, and assemblies across HVAC, electrical, and plumbing trade applications.

Installation Notes

This is a hand tool requiring no installation. Use the short arm for final torque seating and the long arm for rapid fastener spin-down. De-energize electrical equipment and close shutoffs on pressurized systems before removing any fasteners secured by this key. Inspect the ball end for wear or rounding before use on critical fasteners.
