Present on the market for more than 40 years, ESL and ERM have made Lanfranco safety nuts the most recommended safety fastening system for critical assemblies and mounting.

Founded in 1974, J. Lanfranco & Cie specializes in the manufacturing of high-end self-locking nuts. Located in the center of France, our production unit with an area of 5,000 m2, with an extension of nearly 4,000 m2 in progress, is composed of an ultra-robotic machine park and has a large warehouse allowing excellent responsiveness to the needs of our customers. For nearly 40 years, thanks to the quality of its ISO 9001 certified products, our company has been able to win the trust of the largest contractors in the rail, military, aeronautics and energy sectors. In 1997, J. Lanfranco & Cie continued its export development by creating its Canadian subsidiary J. Lanfranco INC. in Montreal. In 2008, attentive to economic developments, our company naturally turned to the South American continent to give birth to Lanfranco AMSUD, our Brazilian subsidiary located in Sao Francisco do Sul.
