## Long description

The Wiha 00978 T-handle hex key is a metric hex key designed for precise tightening and high torque transfer. The blade is made from chrome-vanadium steel, through-hardened and nickel-plated for wear resistance, and the shank includes a recess to accommodate long screws. The Classic Wiha T-handle provides a comfortable grip and good control for repetitive or high-load tasks.
Advantages
Through-hardened chrome-vanadium blade with nickel plating improves durability and corrosion resistance. The Wiha Classic T-handle offers ergonomic support for higher torque while reducing hand fatigue. A recessed shank lets the tool engage long screws securely, and the combination of a 10 cm long arm and 3.2 cm short arm gives both reach and leverage in confined spaces.
Suitable for
Precision assembly and maintenance of machinery and equipment
Automotive and bicycle repairs where high torque is required
Professional workshop tasks and demanding DIY projects
Fastening long hex-head screws or bolts in recessed positions

How to use
Select the T-handle hex key size that matches the hex socket of the fastener. Insert the short or long arm into the fastener depending on required reach and leverage; use the long arm for access in deeper recesses and the short arm when maximum torque is needed. Position the T-handle for a comfortable grip and apply steady force, maintaining alignment to avoid rounding the hex. For long screws, seat the recessed shank fully to ensure engagement.
Usage recommendations
Use the Wiha 00978 for tasks that require controlled high torque. Avoid using the tool as a pry bar or striking it with a hammer. Keep the hex key clean and lightly lubricated to preserve the nickel-plated finish and prevent corrosion; store in a dry place.
