SecosAutoparts 5 x Thread ADAPTERS M8 8MM Male to M6 6MM Female Threaded REDUCERS

Nice 8to6mm thread reducers. If ur running a motorized bike and doing a Minarelli conversion, no need to drill out ur cylinder to accommodate the thicker diameter case studs just Loctite these in and use 130x6mm threaded rod and go

Fix tgreads in head of engine .I like because is precisely just need to be longer.

It works but the metal is weak and start break when inserting the smaller screw.

These work as expected. I did have one break on me while screwing it in, but the others were fine.

The adapter fits and solve my problem.
