What it is
Male XZN impact socket Fervi BI443M005 is a socket wrench with a male insert with XZN profile (12-point), built for use with impact drivers. It is available in a wide range of sizes from M4 to M20, all with an insert length of 25 mm, to cover high-torque tightening requirements.
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 repetitive screwdriving into wood, metal and plasterboard, where torque and consistency matter, 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.
