M16 M18 Stainless Steel Hexagonal Metal Bolt Metal Nut Washer SUS304 SUS316 A2-70 A4-70
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
Material Properties
The M16 and M18 stainless steel hexagonal bolt nut washers are made from SUS304 and SUS316, providing high durability and excellent corrosion resistance. SUS304 is commonly used for its resistance to general corrosion, while SUS316 offers enhanced resistance, especially in environments exposed to chloride and aggressive chemicals. These materials are designed for reliability in both industrial and marine environments.
Advantages
1. Enhanced Corrosion Resistance: SUS304 and SUS316 are highly resistant to corrosion, particularly SUS316, which is ideal for harsh marine or chemical environments.
2. High Strength: The A2-70 and A4-70 grades ensure that these bolts, nuts, and washers can handle high load-bearing applications without failure.
3. Stable Mechanical Properties: These stainless steels maintain consistent performance even under continuous mechanical stress, reducing the risk of failure or loosening.
4. Versatile Applications: These fasteners are suitable for a wide range of applications where high strength and corrosion resistance are required, from industrial machinery to heavy-duty construction.
Applications
These hexagonal bolt nut washer sets are commonly used in high-load industrial applications, such as in steel manufacturing, heavy equipment, marine engineering, and chemical processing. The SUS316 material is especially useful in chemical plants, offshore oil rigs, and any application where exposure to corrosive environments is common.
