Company Overview
Colombo Ezio & C. has been a prominent leader in the fasteners industry since its establishment in 1958 by Colombo Ezio in Abbadia Lariana, Italy. Initially focused on the marketing and production of ring nuts and nuts, the company has undergone significant expansion and modernization. Over the decades, it relocated to Mandello del Lario in 1985 and then returned to Abbadia Lariana in 2001, where it embraced production automation with robotic cells for high-precision manufacturing. The company's commitment to efficiency and quality propelled its expansion into foreign markets, specializing in medium and large series production. In 2017, Colombo Ezio transitioned to Colombo Ezio & C. under new ownership, continuing its international growth. Further solidifying its market position, the company adopted the 'Industry 4.0' philosophy in 2020 and expanded its capabilities through key acquisitions: OSRA SpA in 2021, a specialist in custom-made special parts for sectors like automotive and construction, and CMM Lab in 2022, a company focused on precision machinery.
Products and Services
Colombo Ezio & C. offers a comprehensive range of high-quality fastening solutions. Their product portfolio includes special and security nuts, available in various materials and forms to meet specific customer requirements for dimensions, mechanical properties, coatings, and treatments, including the application of locking inserts.

These are offered in various sizes, threads, and materials such as class 6 steel and spring steel, often galvanized, with stainless steel options available.
A key offering is their self-locking ring nuts, featuring a nylon 6.6 polyamide ring that provides superior locking effectiveness and greater resistance to unscrewing compared to traditional ring nuts. These are made from 14H/22H steel or A2/A4 stainless steel, with various coating options. Additionally, Colombo Ezio & C. supplies standard ring nuts like KM-KML-HM (DIN981), DIN1804, and DIN70852, designed for applications such as restraining bearings or fixing gears and pulleys. These standard nuts are available in different steel grades and stainless steel, with options for induction hardening and various coatings.
