DIN 557 square nuts are connection elements specifically designed for applications requiring a wide surface area. The square shape ensures better contact with the surface where the nut is fixed, facilitating more effective force distribution. Typically made from durable materials such as stainless steel, DIN 557 nuts are used alongside bolts and screw systems to create strong and reliable connections. They are commonly preferred in various industrial sectors, including construction, automotive, and mechanical engineering.
