Wiha 27928 T-handle hex key

The Wiha 27928 T-handle hex key is a VDE-insulated tool designed for working with metric Allen screws. It has a long arm of 15 cm and a short arm of 8 cm, providing good reach and torque while weighing approximately 40 g. The blade is made of chrome-vanadium steel, through hardened with a black finish, and the insulation is moulded directly onto the blade to meet electrical safety requirements. The T-handle offers a comfortable grip for controlled turning of hex fasteners.

Advantages

VDE-insulated T-handle for safe use on live electrical parts up to the rated voltage; chrome-vanadium steel blade is through hardened for durability and a consistent fit in hex sockets; moulded insulation on the blade reduces the risk of exposure of conductive parts; compact weight and T-handle geometry deliver improved leverage and control.

Key specifications

How to use

Select the T-handle hex key size that matches the hex socket of the screw. Insert the short or long arm into the screw head depending on access and required leverage. Apply steady turning force using the T-handle grip; use the long arm for reach or higher torque and the short arm for compact access. When working on electrical installations, ensure the insulation remains intact and observe safe working practices for live circuits.

Recommendations

Inspect the insulation before use and do not use the tool if the moulded insulation or handle is damaged. Use the tool within its intended application and rated standard (IEC 60900) for work on or near live electrical parts. Store in a dry place to prevent corrosion of the blade.
