Precision Fit for Special Nuts: The finely ground hook-shaped jaw precisely engages the grooves of round nuts and ring nuts, accommodating multiple sizes with a secure grip that won't slip. Effortlessly tackle the challenges of installing or removing special nuts.

Effortless and Efficient Torque Transfer: The wrench's ergonomic design optimizes handle length and hook angle, efficiently transferring torque during operation. This reduces effort when tightening or loosening nuts, shortening maintenance time and boosting productivity.

Durable and robust for high-intensity use: Forged from premium alloy steel and treated through quenching and tempering processes, the hook head boasts high hardness and excellent toughness. The handle exhibits strong resistance to deformation, ensuring long-term reliability in demanding automotive and machinery repair applications without wear or damage.
