Adjustment screw M5 for Vespa PK, V50, PX and many other models.
The cable adjustment screw is needed for the clutch and gearshift, among other things.
The hollow screws are considered wearing parts. They wear out over time due to the friction of the cable. Due to the low wall thickness, there is a risk that the screw could break off, especially if it is screwed out too far.
