Hexagon head nut Stainless Steel SS304 SS316
Product Description
Stainless steel Stainless Steelrefers to steel resistant to corrosion in air, steam, water and chemical corrosive medium, such as acid, alkali and salt, also known as stainless steel.
hex nut is a nut which is screwed together with a bolt or screw to serve as a fastening part . All production and manufacturing machines must be an original . There are many kinds of nuts . The nuts and nuts are divided into high strength , national standard , general standard and common few types according to different materials .
the nut is a tightly connected part of the machine, which is tightly connected to the screw through the inside thread.
tainless steel is a modern material with 60 years' development
In 19th century, the inventor of stainless steel was Henry Bradley, a British metallurgical expert.
Plain color, blackened, galvanized generally are common carbon steel nuts. Nuts generally have performance grade. Stainless steel generally is A2-70. when distinguishing carbon steel nuts and stainless steel nuts with a magnet to know. Stainless steel will not be absorbed by magnets. Stainless steel products are usually bright silver.
Specification
| Type | hex nut heavy hex nut |

Application
The nut is made of stainless steel , stainless steel nut , stainless steel nut , stainless steel nut , square nut - C , cap nut , stainless steel hex nut , square nut - C , and cap nut .The thickness of M nut is thicker, more often required for the regular assembly and disassembly occasions. The thickness of M six angle thin nut is thin, multi connected parts of the surface for space constrained occasions.
Advantage
The advantages of stainless steel
Compared with carbon steel, stainless steel has the following characteristics:
1) the resistivity is about 5 times higher than that of carbon steel.
2) the large coefficient of linear expansion is 40% larger than that of carbon steel. With the increase of temperature, the value of the coefficient of linear expansion is also increased.
3 ) Low thermal conductivity , approximately 1 / 3 of carbon steel
Nut is used for bolt or screw fastening screw together to the function of parts, all production machinery must use an original.Suitable Bolts, Hex cap Screw, and studs for use with nuts included in this specification are covered by Specification F593,Unless otherwise specified, All bolts, hex cap screw, and stud used with these nuts shall conform to the requirements.
Stainless steel nut is our common type of fastener products, it is mainly used in conjunction with stainless steel bolts, relative fastening effect.
Hex nut (Hexagon nut) used with bolt, screw, connecting the fastening parts.Also divide into stainless steel nuts and zinc plated carbon steel nuts. Among them the most widely type 1 hexagonal nut, class C nut is used for surface is rough, the accuracy is not high on machinery, equipment or structure;Class A and class B, nut is used for surface is bright and clean, high requirements for accuracy of the machinery, equipment or structure.Type 2 hexagonal nut thickness m thicker, more used to often occasions often require.The thickness of the thin hexagonal nut m thinner, more used to be the surface of the connection parts place restricted space.
Hexagon nuts according to the nominal thickness is divided into type I and type II and three thin.More than 8 nut is divided into two type type I and type II.
Type I of the most widely hexagonal nut, nut and type 1 points A, B, C level 3, which class A and class B, nut is suitable for the surface roughness is small, the high accuracy requirement of machinery, equipment and structures, and class C nut is used for surface is rough, the accuracy is not high on machinery, equipment or structure;Type 2 hexagonal nut thickness is thicker, more in occasions often require.
Nut is nut type 1 m nominal height of 0.8 D or regular hexagonal nut, the type size shall comply with the provisions of GB/T6170;
And the height of the 2 type nut than type 1 nut, the type size should comply with GB/T6175.2 type nut has two: the purpose of the one is by increasing the height of the nut to get a low without heat treatment, comparison of nut.
We are very competive on this nut, If you have more questions,Please contact us by email : me@hainafastener.com
