What it is
Impact universal joint Fervi JI402N. Key specifications: square connection 3/4", d (mm) 44, length (mm) 90.
The universal joint, also called a cardan joint, is an articulated joint with a square drive at each end, which allows fastening with the machine at an angle to the nut.
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. Use it only when it is not possible to align with the nut, because at steep angles it transmits less torque and wears faster. Start slowly, holding the machine steady, and discard joints with excessive play or cracks. On impact wrenches, use impact universal joints.
