Planetary gear wrench STT-58 1:64 6000Nm

The professional STT-58 torque multiplier is a reliable tool designed for situations where conventional methods fail – especially when dealing with over-tightened or seized wheel nuts. Until now, loosening such bolts often required heavy pneumatic tools or long, unwieldy extensions.

With a 1:64 gear ratio and a maximum torque of 6000 Nm, the STT-58 delivers powerful performance without the need for a power source – perfect for any location or working condition.

A 1:1 direct drive option is also available using the included hand crank and extension – no external tools required.

The design emphasizes portability, packed in a compact case (36 × 21 × 9.5 cm) that fits easily in almost any vehicle. The total weight of the set is 7.6 kg (tool alone: 4.2 kg).

Equipped with a 1" drive, it is compatible with standard workshop sockets. The set includes two durable CrV (chrome-vanadium) sockets: 32 mm and 33 mm.

Each STT-58 unit features a laser-etched spec marking, ensuring precision and high manufacturing quality.

The STT-58 is a must-have for truck drivers, and operators of construction or agricultural machinery!
