Stainless steel is one of the most employed materials for the production of screws, bolts, and other fasteners. Fasteners manufactured in stainless steel are applied in almost all industrial sectors.
According to national and international standards, fasteners have to follow specific naming schemes with the purpose of identifying and making manufacturing processes homogeneous.
Both bolts and nuts generally have notations made, in relief or engraved by the manufacturer that define their basic characteristics.
Knowing and understanding these notations is very important for their correct use.
Metal coatings are treatments largely used in various areas of the mechanical engineering industry with the purpose of protecting their surface from normal destructive forces and prolonging the lifespan of metal parts or change their aspect. They vary depending on the kind of material involved, purpose and process applied.
Bolts and screws are two of the most used and helpful types of fastener. Both are largely utilised in all manufacturing and construction industries.
Albeit they have specific features that make them suitable for different applications, often a clear distinction between them is not easy to define.
