About us

Colombo Ezio

Our history dates back to 1958, when our founder Ezio Colombo decided to start a company for the manufacturing of ring nuts and nuts. Since then we have been growing and we created for ourselves an image as a reliable provider in various industrial sectors on the international scenario.

Over the years our recognized know-how and expertise, combined with our efficiency and sustainability, let us take hold of a leading role in the fastener industry.

A matter of DNA

Ring-nuts are in our DNA – Ezio’s dedication has been passed down through the generations. Our main focus is our customers’ satisfaction – we manufacture a wide range of products, from standard ring nuts to self-locking ring nuts, and even special ring nuts, designed according to the customer specification.
