1. What is a hexagonal head nut?

Hexagon nuts, or hexagon nuts, are a common connecting element used in mechanical parts. They are usually used together with screws and bolts to connect two or more components. Depending on the standard specifications, hexagon nuts are categorized into several models, such as M1-M64. There are also different materials, including stainless steel and carbon steel. Hexagonal nuts and screws, bolts, and screws are used in conjunction with each other to connect the role of fastening machine parts. Among them, 1 type of hexagonal nuts is most widely used; c grade nuts are used for the surface is relatively rough, the precision requirements of the machine, equipment, or structure; A-grade and B-grade nuts are used for the surface is relatively smooth, the precision requirements of the machine, equipment or structure. 2 type hexagonal nut thickness M is thicker and is used for the occasions that often need to be mounted and dismounted. Thin hexagonal nuts are thinner in thickness M and are used mainly when the surface space of the connected machine parts is restricted.

2. What are the characteristics of hexagon nuts?

According to the nominal thickness, hexagonal nuts are divided into I-type, II-type, and thin three types. Eight or more nuts are divided into 1-type and II-type two types. I-type hexagonal nuts are the most widely used, and 1-type nuts are divided into A, B, and C three levels, of which A and B level nuts are suitable for the surface roughness of the small, high precision requirements of the machine, equipment, and structure, and the C-level nuts are used for the surface is relatively rough, high precision requirements of machines, equipment or structure; 2-type hexagonal nuts are thicker, more often used in occasions that usually require assembly and disassembly. The thickness of type 2 hexagonal nuts is denser and is mainly used on occasions that frequently need to be assembled and disassembled.

Type 1 nut refers to the nominal height of the nut m ≥ 0.8D of the ordinary hexagonal nut; the type size should be in line with the provisions of DIN934, and the height of the 2-type nut than the 1-type nut should be higher, the type size should be in line with the GB/T6175. 2-type increase in the purpose of the nut: one is to get through the rise in the nut's height, which does not need to be heat-treated; the cheaper the nut. Because D ≤ M16 8 level 1 type of nuts do not require heat treatment, in 8 level nuts, only D> M16 ~ 39 specifications with two kinds of nuts do not need heat treatment 1 type of nuts can not reach the mechanical properties of the 9 level of nut requirements. Another purpose of the provisions of the 2-type nut is to obtain better toughness than the 12-level nut. As the height of the nut increases, the lower quenching and tempering hardness can be achieved to ensure that the stress indicators increase the toughness of the nut.

Classification by material: stainless steel hexagonal nuts and carbon steel hexagonal nuts, copper hexagonal nuts, iron hexagonal nuts.

Classification by pitch: standard teeth, regular teeth, fine teeth, excellent teeth, and reverse teeth.

Classification by thickness: hexagon thick nuts and hexagon thin nuts.

Classified according to the use of methods: hot melt copper nuts, hot pressing copper nuts, embedded copper nuts, and ultrasonic copper nuts

Hexagonal nuts have some unique characteristics. First, they have a hexagonal shape, which makes them easier to use with tools such as wrenches and easy to install. Secondly, hexagonal nuts have a specific shear strength and can withstand large shear forces. In addition, hexagon nuts have a solid and reliable connection that is not easy to loosen. These features make the hexagon nuts widely used in machinery, construction, and other fields.

3. What are the common materials for hexagon nuts?

The common materials of hexagon nuts include carbon steel, stainless steel, copper, aluminum alloy, titanium, etc. Carbon steel hexagon nuts are solid, inexpensive, and widely used in machinery and heavy equipment. Stainless steel hexagon nuts are highly corrosion resistant and aesthetic, suitable for frequent contact with water and humid environments in equipment, such as ships and kitchen equipment.

4. What are the specifications of hexagon nuts?

A Hexagon nut is a typical self-locking nut installed on the threads of a bolt and rotationally adjusted by the hexagonal structure at its top, which is suitable for occasions of fixing and connecting fasteners. They are usually used in mechanical, electrical, construction, and automotive fastener connections. The external hexagonal nut is a fastener widely used in machinery, engineering, construction, and other fields. Its size specifications are as follows:

M2,M3,M4,M5-0.80; M6-1.00; M8-1.25; M10-1.50; M12-1.75; M14-2.00; M16-2.00; M18-2.50,M20-2.50,#6-32,#4-40,#8-32,1/4-20",5/16-18,3/8-16",1 /2-13'.

5. Surface treatment of hexagon nuts

Hexagon nuts are commonly used fasteners in mechanical equipment, automotive, aerospace, and other fields. To improve their corrosion resistance, abrasion resistance, and aesthetics, hexagon nuts are often treated with a surface treatment. Below, Artisan Xin will introduce the surface treatment of hexagon nuts, including zinc plating, zinc-nickel alloy, Dacromet, nickel plating, chrome plating, spraying, oxidation, phosphating treatment, and so on.

Zinc plating: Zinc plating is a surface treatment that covers the surface of hexagon bolts with a zinc layer. Zinc has excellent anti-corrosion properties and can effectively prevent corrosion and oxidation of hexagon bolts. Galvanization methods include hot-dip galvanizing and electro-galvanizing, two kinds of zinc, of which hot-dip galvanizing has better anti-corrosion properties.

Electro galvanized zinc-nickel alloy: Electro galvanized zinc-nickel alloy is a metal material used for surface treatment, which can provide high corrosion resistance, abrasion resistance, and heat resistance, as well as excellent appearance. Electroplated zinc-nickel alloy is composed of zinc and nickel, which can be electroplated to form a protective film on the metal surface, thus improving the metal surface's corrosion resistance, abrasion resistance, and heat resistance.

Dacromet: Dacromet is the translation and abbreviation of DACROMET, also known as Dacromet, Dacron Rust, and Dicron. Domestically known as zinc-chromium coating, it is a new type of anticorrosive coating with zinc powder, aluminum powder, chromic acid, and deionized water as the main ingredients.

Both Dacromet and electroplating are surface treatment technologies. Dacromet is an advanced anti-corrosion technology, also known as passivation treatment technology, which is a plating through the formation of an oxide layer on the surface of the metal to play a role in corrosion resistance. Electroplating is a metal surface treatment method based on electrolysis, which deposits a layer of metal or alloy plating on the surface of the workpiece through an electrochemical reaction, thus playing the role of corrosion resistance or aesthetics.

Nickel plating: Nickel plating is a surface treatment method to cover the surface of hexagon bolts with nickel layers. Nickel has good corrosion and wear resistance, which can effectively extend the service life of hexagon bolts. Nickel plating methods include electroplating nickel and chemical nickel plating, which is more costly but has better corrosion resistance.

Chromium plating: Chromium plating is a surface treatment that covers the surface of hexagon bolts with a chromium layer. Chromium has excellent corrosion resistance and aesthetics, which can make hexagon bolts more durable and beautiful. Chrome plating methods include electro-chrome plating and chemical chrome plating, which is more costly but has a better surface luster.

Spraying: Spraying is a surface treatment involving spraying paint on hexagon bolts' surfaces. Spray coating can be selected according to the need for different types and colors, making the hexagonal bolts more beautiful and corrosion-resistant. Spraying methods include spraying paint and powder, the cost of which is lower, but the corrosion resistance is poorer.

Oxidation: Oxidation is a surface treatment method that forms an oxide layer on the surface of hexagonal bolts. The oxidized layer has excellent corrosion and wear resistance and can protect the hexagonal bolts. Oxidation methods include anodic oxidation and sulfuric acid oxidation, of which anodic oxidation is more costly but better corrosion resistant.

6. Precautions for selecting hexagonal nuts

When using hexagon nuts, the following points should be noted:

6.1. Select a suitable size and material. According to the actual need, select the appropriate size and material with corrosion resistance, high-temperature resistance, tensile strength, and other properties.

6.2 Confirm the thread direction. Hexagonal nuts and bolts must be used together; the bolt's thread direction must be the same as the nut's to avoid tightening difficulties, thread destruction, etc.

6.3 The tightening force is appropriate. Too tight will lead to deformation of the nut, while too loose is easy to loosen, so you need to adjust the tightening force.

6.4 Tighten in the right way. To avoid damage or falling off, the nut should be tightened using the specified method, such as hand wrenches or power tools.

The above are a few points to note when using hexagon nuts. Please comply with the relevant specifications and precautions when using them.

Conclusion: Hexagon nuts are commonly used fasteners. We have detailed their size specifications and precautions for you. If you need to buy or use hexagon nuts, choose the right size and material and follow the relevant norms and precautions to ensure safe and reliable use.

In short, hexagon nuts are one of the indispensable components of mechanical connections, with their unique hexagonal shape, shear strength, and solid and reliable connection effect, all for installing and using mechanical parts to provide convenience.
