M3 M4 Stainless steel Hexagon Nuts SS304 SS316 A2 A4-80 Hex bolt with hex nuts Metal Nut
Product Description:
Hexagonal nuts and screws, bolts, screws used in conjunction with each other, to connect the role of fastening machine parts. One of the most widely used by the 1 type of six nuts, C nuts for surface roughness, the precision requirements of the machine, equipment or structure is not high; A and B nuts for the surface is more polished, the precision requirements of the machine, equipment or structure. 2 type hexagonal nut thickness M is thicker, more often used for often need to be mounted and dismounted on the occasion. Thin hexagonal nuts are thinner in thickness M, and are mostly used on occasions where the surface space of the connected machine parts is restricted.
Hexagonal nuts in accordance with the nominal thickness is divided into I type, II type and thin three kinds of nuts above level 8 is divided into 1 type and II type two types. I type hexagonal nuts are the most widely used, 1 type of nut is divided into A, B, C three levels, of which A and B level nuts are suitable for surface roughness is small, the precision requirements of the machine, equipment and structure of the high level, while the C level nuts are used for the surface of the rougher, the precision requirements of the machine, equipment or structure; C level nuts for rough surface, the precision requirements of the high level. The thickness of type 2 hexagonal nuts is thicker, and they are mostly used in the occasions that need to be assembled and disassembled frequently.
Applications
How to match the grade of bolts and nuts? If the bolt is grade 8.8, what grade should the nut be?
Metric bolt grade: 4.6; 4.8; 5.8; 6.8; 8.8; 9.8; 10.9; 12.9.
Metric nut grade: 4; 5; 6; 8; 10; 12 where 4; 5 is the strength level of thin nuts.
So: bolts with 8.8 grade, nuts with 4 grade, this makes sense?
First of all: 8.8 and 4 level is too unscientific.
General selection of bolts to remove the grade behind the decimal is the grade of the nut, 8.8 grade bolts with 8 grade nuts, 10.9 grade bolts with
10 grade nuts.
That is, the bolt, nut strength level is the same (bolt 8.8 and nut 8 strength level is the same, because the bolt after the ‘.8’ that is the yield strength is 80% of the tensile strength.)
But consider the use of the situation if the nut is not easy to replace, the bolt is easier to replace, can also be changed to bolt 4.8 nut 5.
There are occasions when the strength of nuts is a little lower than that of bolts, mainly because the failure of bolts is usually not easy to detect, sometimes suddenly, whereas the failure of nuts is easier to detect. The safety aspect is also taken into account. This ensures that when used in conjunction, the life of the screw is longer than the nut, and so that when removing and replacing fasteners, the cost will be cheaper and easier.
