Wiha 36998 Ball End Hex Key Set 13 Piece

Product Description

The WIHA 36998 is a 13-piece L-key ball end hex key set designed for professional fastener driving in tight or angled access situations. Built from Chrome Vanadium Molybdenum steel, these keys deliver the toughness and torque capacity that trade professionals expect on the job. The ball end tip allows engagement at off-axis angles, letting technicians drive fasteners without perfect tool alignment. The long-arm style increases torque leverage on the straight end while the short arm provides high-speed rotation. This set covers a hex range from 0.050 inch to 3/8 inch, making it a wide-coverage option for HVAC, mechanical, and electrical service work.

This set is suited for residential and commercial service environments where panel access, equipment assembly, or set-screw adjustment is routine. HVAC technicians, electricians, and mechanical contractors will find the range of sizes practical for blower wheel set screws, electrical panel hardware, and equipment mounting fasteners. The long-arm L-key format is especially useful when working inside equipment cabinets or tight enclosures where a standard driver cannot reach.

Key Features

• Ball end tip allows fastener engagement at off-axis angles for restricted-access applications
• Chrome Vanadium Molybdenum steel construction for durability and high torque resistance
• Long-arm style provides increased leverage on the straight end
• 13-piece set covers 0.050 inch through 3/8 inch hex sizes
• L-key format gives two driving options: high torque on the long arm, fast rotation on the short arm

Compatibility

Designed as a general-purpose inch hex key set compatible with standard hex socket fasteners across HVAC, electrical, plumbing, and mechanical service applications.

Installation Notes

No installation is required for hand tools. Confirm the correct hex size before applying torque to avoid rounding fastener sockets. When using the ball end at an angle, reduce applied torque to prevent tip wear or fastener damage. Store keys in a dry environment to prevent corrosion of the steel alloy.
