Hexagon nuts are also called hex nuts. There are many kinds of general nuts, such as hex nuts, round nuts, square nuts and so on.
Some of the standards for nuts are clear. Standard of size of a few specifications, qualitative requirement standard, electroplating standard is clearer.
And different types of nuts also have different standards, detailed introduction of nut specifications and standards.
Hexagon nuts and screws, bolts, screws with the use of the connection fastening parts.
Among them, the most widely used type 1 six-purpose nuts, C-class nuts for rough surface, the precision of the machine, equipment or structure is not high.
Class A and class B nuts are used for machines, equipment or structures with relatively smooth surfaces and higher requirements for precision.
Type 2 hexagon nut thickness M thicker, more often used in the need to assemble and disassemble the occasion.
Hexagon thin nut thickness M is thin, more used to be connected to the surface space of the machine is limited occasions.
Step welding nut is a step nut suitable for welding outside the nut.
It is generally made of weldable materials and thick for welding. Welding is equivalent to turning two separate parts into a whole.


After melting the metal at high temperature, it is mixed together and then cooled.
Welding, the strength is relatively large, and the use of a wide range of thickness can be, but due to high temperature will lead to the deformation of the connecting piece, and can not be disassembled.
Moreover, some active metals can not be welded by the usual methods.
The welding parameter test depends on the fusion size of the weld, and the welding parameters are adjusted according to the fusion size until the defects are eliminated.
Of course, the quality of welding is related to welding pretreatment, dust removal, oil stains and so on.
Hexagon nuts are widely used. Hexagon nuts are used for machines, equipment or structures with rough surface and low precision requirements.
Custom-made hexagon thick nuts are used for machines, equipment or structures with relatively smooth surface and higher requirements for precision.
Hexagon thick nut thickness is thicker, more often used in the need to assemble and disassemble the occasion.
Hexagon thin nut thickness is thin, more used to be connected to the surface space of the machine is limited occasions.
Nuts are fasteners with internal threads that are used with bolts to transmit motion or power.
