GEOMET® 500 is a high-performance anti-corrosion system, applied for the treatment of steel, cast and other ferrous metal parts that provide optimal results in terms of friction as well. It is largely used by some of the main automotive manufactures around the world because it respects their strict standard of quality. (more…)
Burnishing or black oxidation or black oxide or chemical black
This protective coating consists in two different procedures.
A bolt is a type of fastener, that is normally used together with a nut for assembling two unthreaded components.
The ease to use made them suited to play an important role in the development of mass-produced articles and steel structures.
Vipa’s customers have at their disposition a vast range of fasteners manufactured according the main International standards as ISO, EN, DIN, UNI and ANSI.
But what is a standard and why is essential to know the meaning of that acronyms for a more mindful purchase of fasteners.
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.
Self-tapping screws are one of the most important types of commercial fasteners in use today. The reasons for their success lie on their characteristics of versatility, handiness and reliability. (more…)
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.
