Fastener is a kind of mechanical part widely used for fastening and connection. It is characterized by various varieties and specifications, different performance and uses, and high degree of standardization, serialization and universality. Therefore, some people also call a type of fastener in the standard standard fastener, which is called standard fastener for short.
What are the main uses of fasteners:
Fasteners are mainly used in energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, mold, hydraulic and other fields. There are various fasteners on all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies. Fasteners are also known as the most widely used mechanical basic parts.
Introduction to fasteners:
Fasteners include: bolts, studs, screws, nuts, washers and pins. Fasteners made of stainless steel, aluminum alloy and titanium alloy will lock or bite. The fasteners themselves have corrosion resistance and form a thin oxide layer on the metal surface to prevent further corrosion when the surface is damaged.
When the stainless steel is locked, the heat between the teeth will be cut off or the metal locking layer will be blocked, resulting in the destruction of the locking layer. When this happens, the stainless steel fasteners are fully locked and can never be removed or locked. This blocking shear bonding locking sequence usually occurs within a few seconds, so we should correctly understand this kind of fastener when using it, so that this phenomenon can be prevented.
