Nuts, manufactured from various metals and plastic, are a type of fastener with a threaded hole. They are almost exclusively used to mate with a bolt that has the correct threading pattern.
The friction of the bolt and nut threads against one another creates a temporary joint that holds material together.
In Vipa nuts are available in different sizes and shapes for a wide range of purposes.
Nickel electroplating is a coating process that consists in covering the surface of the metal with a thin layer of nickel (3 µm) by means of electrolysis. In practice the metal is submerged into an electrolyte solution that allows the transfer of nickel ions onto the material that has to be treated. (más…)
Machine screws are a smaller type of screw, threaded along the entire length of their shank. They are designed to engage with already threaded nuts or threaded holes and are largely employed to fasten metal parts together in all types of machines and industrial manufacturing equipment.
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. (más…)
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. (más…)
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.
