stainless steel SS304 SS316 DIN912 Hexagon socket head cap screws
Description:
Hex nut (Hexagon nut) used with bolt, screw, connecting the fastening parts.Also divide into stainless steel nuts and zinc plated carbon steel nuts.
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.
Apparently without heat treatment of type 1 nut can not meet the requirements on the mechanical properties of the 9th nut.Rule 2 type nut another purpose for toughness better grade 12 nut.By increasing the height of the nut, under lower quenching tempering hardness can reach guarantee stress index, thus increase the toughness of nut.
According to standard tooth distance classification: teeth, normal tooth, tooth, very fine teeth and the teeth.
According to the material classification: stainless steel hexagonal nut and carbon steel hexagonal nut, hexagonal nut of copper, iron hexagonal nut.
According to the thickness of classification: hexagon nuts and thick thin hexagonal nut.
According to the classification method of use: hot melt copper nut, hot pressing copper nut, embedded copper nut and ultrasonic copper nut.
We are very competive on this nut and have many stock in it. If you have any questions,Please contact me by email

Description:
The inner cylinder head Allen screws, also called hex bolts, cup head screws, socket head cap screws, its not the same name, but represent the meaning is the same. Commonly It is called hexagon socket head screws, then there are 4.8, 8.8, 10.9, 12.9. Also called SHCS, also called hex bolts. Its head is hex head, cylinder head also. Material stainless steel and iron. There are stainless steel SUS202 stainless steel hexagon socket head cap screws, this is an ordinary stainless steel material, there are stainless steel SUS304 hexagon socket head cap screws with stainless steel SUS316 hexagon socket head cap screws. Iron by hexagon socket head cap screws strength rating, there is within 4.8 hexagon socket head screws, there are within 8.8 hexagon socket head cap screws with internal hexagon socket head cap screws 10.9 with 12.9 hexagon socket head cap screws. Within 8.8 -12.9 level hexagon socket head cap screws called high-strength high-grade hex bolts. Standard StandardNo: GB / T 70.1-2008. The most common stainless steel for general hardware use is stainelss steel 304, which is also called stainless steel 18-8.Stainless steel 316 is A highly corrosion resistant grade of stainless steel. Ideal in salt water and chlorine environments. More expensive than 18-8. Zin plated alloy steel is another a very high strength heat treated alloy steel. Zinc plated for moderate corrosion resistance. Alloy steel black oxide finish is also a very high strength heat treated alloy steel. Black oil (plain) finish. ASME standard socket cap screws are from 0 to 2" diameter. These socket cap screws are manufactured to the most recent ASME B18.3, IFI, or customer stated standards with either full or partial threaded options. Our stockisthousands of these socket cap screws in any of our various materials and sizes.
