Allen bolt M8x90 for Vespa exhaust original

Original Allen bolt in size M8 x 90 for the exhaust suspension of Piaggio and Vespa

These bolts rust like crazy. It is also important that you do not damage the Allen 6, otherwise you will never get it loose again.

Be smart and replace it in time. Because if you can't get it loose anymore, you're in trouble. You won't be the first to have to drill it out or work with a long bolt and a nut on the back (a DIY solution!). Do it the right way and put in a new and original bolt.

Measure yourself to see if it is the right size. The length of the thread to the Allen head should be 90mm. Some exhaust bolts are a bit shorter, e.g. 60, 70 or 75 mm.
