What it is
The Fervi I306 series comprises long impact sockets in sizes 17, 19 and 21 mm, with a length of 150 mm that makes it possible to reach nuts and bolts in deep positions or on protruding studs. The set has a gross weight of 1.42 kg.
Impact sockets are reinforced sockets for use with impact wrenches, together with extensions, universal joints and adapters that fit the tool's square drive.
What it is for
Used for vehicle maintenance, in the workshop and on the road and for tightening nuts and bolts where torque must be accurate and repeatable.
How to use it
Choose a socket of the exact size of the nut and with the same square drive as the impact wrench, or use an adapter. Push it on until the detent ball or retaining ring clicks home, adding an extension or universal joint only if needed to reach the nut. On impact tools, use only impact-rated sockets and accessories, as chrome hand sockets can shatter. Discard sockets with a worn-oval or cracked opening.
