Planetary gear wrench STT-88 1:64 6000Nm + sockets

The STT-88 gear wrench is an essential solution wherever there are issues with severely seized or overly tightened bolts and nuts – particularly on wheels of heavy-duty vehicles, agricultural equipment, or construction machinery. When standard hand tools fail and pneumatic tools aren’t available, this wrench proves its worth.

The tool delivers reliable technical performance – with a 1:64 gear ratio and a torque of up to 6000 Nm, it provides enough power to loosen even the most stubborn fasteners. Fully mechanical and requiring no power source, it’s perfect for use in the field.

Additionally, the set allows operation in direct-drive mode (1:1), bypassing the gearing system. The handle with extension enables quick removal of bolts that were previously loosened, significantly speeding up the workflow.

All components are neatly packed in a durable plastic case (dimensions: 40 × 32 × 9 cm), making it easy to store in any vehicle. The total weight is 10.9 kg, with the wrench itself weighing about 4.6 kg – a balance between robustness and portability.

The kit includes seven of the most commonly used sockets made of chrome vanadium steel (CrV): 24, 27, 30, 32, 33, 36, and 38 mm. The addition of chromium and vanadium enhances the steel’s hardness and wear resistance, making the sockets a dependable choice for workshop and field use.
