The WIHA 37192 is a 10-piece L-handle Torx key set covering sizes T6 through T30, including T10, T15, and T20. Manufactured from alloy steel, these keys are built for the torque demands of field and bench service work. The long-arm L-handle design gives technicians leverage for driving fasteners and a shorter grip end for working in tight spaces. The set ships in a pouch for organized storage and transport. HVAC, electrical, and general service professionals will find this set useful for equipment panels, motor assemblies, and control component fasteners that rely on Torx drive profiles.
This key set is suited for residential and commercial service work where Torx fasteners appear on equipment enclosures, fan assemblies, control boards, and access panels. The T6 to T30 range covers the Torx sizes most commonly encountered across HVAC equipment, electrical panels, and mechanical assemblies. The included pouch keeps keys sorted and accessible during a service call or in a tool bag.
Designed for use with standard Torx drive fasteners in the T6 to T30 size range, as found on HVAC equipment, electrical enclosures, and mechanical assemblies across residential and commercial applications.
Select the correct Torx key size before applying torque to avoid fastener damage or key slippage. De-energize and lock out equipment before accessing panels or assemblies secured with Torx fasteners. The L-handle design is not intended for use with power tools or impact drivers. Follow applicable NEC or equipment manufacturer service procedures when working inside energized enclosures.
