Why Benevelli use key-less system thanks to the advantages of "interference fit". In an interference fit, the inner part is machined to be bigger than the mating hole of the outer part. The larger part is then forced into the smaller part. Both parts deform slightly to fit together and extremely high friction results between them. The friction is so great that even large amounts of torque cannot separate the parts. They operate as one. #interferencefit #keylesssystem #astepahead #benevellifacts #benevelliproducts #advantages #engineering https://www.instagram.com/p/Boq5iLkiEWM/?utm_source=ig_tumblr_share&igshid=kr6rsygemtos
