Black M10 M16 Carbon steel hexagon nuts Class8. 8 Grade 8.8 Extended Thin hex nut

Black M10 M16 Carbon steel hexagon nuts Class8. 8 Grade 8.8 Extended Thin hex 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.

The design of hexagonal nuts gives them good torque transmission capacity and can withstand large axial and radial loads.
1. Construction:In the construction industry, hexagonal nuts are commonly used in the connection of steel structures, steel frames and bridges to ensure the stability and safety between structural components.
2. Mechanical engineering: In the field of mechanical engineering, hexagonal nuts are used to fix various parts of mechanical equipment, such as automobiles, ships, aviation and machine tools, etc., in order to ensure the normal operation and long-term stability of the equipment.
3.Electronics:Some electronic products use snap screws, which are actually a special type of hexagonal bolt, to ensure the tightness and stability of electronic components.
4. Home maintenance:In daily life, hexagon nuts are also often used in furniture assembly, bicycle repair and other home maintenance work.
In addition, hexagon nuts have a variety of classifications and specifications to meet different engineering needs. For example, category 1 hexagon nuts have single-sided chamfers, while category 3 hexagon nuts have double-sided chamfers. Pocket nuts, which have screw holes that do not run through their profile, are commonly used for decorative purposes, especially in applications such as playground equipment where the unterminated end of the bolt may be a hazard. Butterfly nuts, on the other hand, are commonly used in applications where space is limited, such as on automobile wheels.

Applications

Stainless steel has several key performance characteristics.

1. Strong corrosion resistance: stainless steel has excellent corrosion resistance, and can maintain stable performance in humid, acid and alkali and other harsh environments.

2. Good oxidation resistance: stainless steel can withstand high temperatures and oxidation, not easy to oxidation reaction, so as to maintain the bright luster of the surface.

3. Excellent mechanical properties: stainless steel has high strength and hardness, and can withstand large external forces and pressures.

4. Hygienic and reliable: stainless steel material is non-toxic, does not produce odour, has good hygienic properties, widely used in food and medical fields.

Classification
(1) According to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and free-cutting structural steel three categories, carbon structural steel is divided into engineering construction steel and machine building structural steel two;
(2) According to the smelting method can be divided into flat furnace steel, converter steel;
(3) According to the method of deoxidation can be divided into boiling steel (F), sedentary steel (Z), semi-sedentary steel (b) and special sedentary steel (TZ);
(4) According to the carbon content of carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC ≥ 0.6%);
(5) according to the quality of steel can be divided into ordinary carbon steel (containing phosphorus, sulphur higher), high-quality carbon steel (containing phosphorus, sulphur lower) and high-quality steel (containing phosphorus, sulphur lower) and high-quality steel.

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.
