Pneumatic Impact Wrench 1700 Nm 1/2" STIX STT-17 Composite + Long CR-MO Impact Sockets 17/19/21 mm + Case with Oiler
In a set
STT-17 pneumatic impact wrench + STT carrying case + long CR-MO impact sockets 17/19/21 mm
This set includes the STT-17 pneumatic impact wrench together with an STT carrying case and three long CR-MO impact sockets in sizes 17, 19 and 21 mm. It is a functional solution for workshops and garage users who need an efficient impact tool and durable sockets suitable for common wheel bolts and other threaded connections.
The STT-17 wrench uses a Twin Hammer mechanism that reaches full impact power from the first rotations, enabling efficient loosening of seized or corroded fasteners. The four-level torque adjustment allows the tool to be matched to different tasks, while the glass-fibre-reinforced composite housing withstands workshop conditions and contact with oils or chemicals. The soft-grip handle improves stability and reduces vibration during longer work sessions.
The STT carrying case provides secure storage and safe transport of the wrench and accessories. Made from durable plastic, it protects the tool from impacts, while the interior layout keeps components properly positioned. The included mini inline oiler enables lubrication directly through the air system, which helps maintain the efficiency and lifespan of the impact mechanism.
The set also includes three long CR-MO sockets in sizes 17, 19 and 21 mm. Made of chromoly steel, they withstand high loads, impact forces and elevated temperatures. Their extended design allows access to deeper bolts, while the six-point profile reduces the risk of slipping on worn fastener heads. Permanent laser markings ensure quick identification of each size.
This kit provides a practical combination for tyre services, mechanical workshops and home garages, offering reliable impact performance, organized storage and access to the most commonly required socket sizes.
