M7 x 54 mm screw for the engine housing, compatible with your Vespa Largeframe and Smallframe scooters. You can find a list of the exact models below in the drop-down menu under “Compatible with the following models.”
This housing screw—or tie rod—is used for the standard fastening of the two halves of your scooter’s engine housing. Unlike stud bolts, the housing bolt is not screwed into the engine housing itself, but is instead threaded through the through-hole in both housing halves and then secured on one side. The opposite end features a head without a keyway and is equipped with an anti-rotation device. This allows the engine housing to be properly clamped, as is intended for numerous classic Vespa engines.
You can find matching hex nuts, additional bolts, and bolt sets in the accessories section.
