What it is
Impact extension bar for socket wrenches Fervi PI403250. Key specifications: connection 1/2", length (mm) 250, diameter (mm) 25.
The socket extension is a rod with a square male drive at one end and a female drive at the other, which extends the drive to reach recessed nuts.
What it is for
Used in mechanical maintenance of machinery and plant, during scheduled shutdowns or breakdowns, 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
Fit it between the machine and the socket until the retaining ball clicks, choosing the shortest length needed. The longer it is, the less rigid and accurate it becomes, so keep the machine aligned with the axis. On impact machines, use only impact extensions.
