M16 M18 Stainless Steel Hexagonal metal Bolt and Nut Washer SUS304 SUS316 A2-70 A4-70

The M5 and M6 stainless steel hexagonal bolts with nut washers are essential fasteners for medium to heavy-duty applications. Made from high-quality SUS304 and SUS316 stainless steel, these bolts offer exceptional strength and resistance to corrosive environments. They are often used in machinery, automotive, and construction applications, providing secure, long-lasting connections.

Applications of half-threaded fasteners:
The presence of a smooth shank section facilitates positioning and adjustment during installation and removal.
This smooth section also reduces material usage, thereby lowering costs.
Consequently, half-threaded fasteners are frequently employed in applications where full-threaded connections are unnecessary, such as bolts fitted into holes. Here, the smooth shank acts as a guide, enabling smooth insertion of the bolt into the hole.

• High Corrosion Resistance: The SUS304 and SUS316 materials provide exceptional resistance to rust, oxidation, and corrosion, especially in harsh environments.
• Grade Options: Available in A2-70 and A4 grades, these bolts offer different levels of tensile strength, making them adaptable to various requirements.
• Reliable Performance: The hexagonal design of the bolt ensures easy installation and secure fastening with a hex wrench.

• Durability: These bolts are highly durable, ensuring that your assembly remains intact for extended periods, even under heavy loads.
• Low Maintenance: Stainless steel's resistance to corrosion and staining means minimal upkeep is required for long-term reliability.
• Versatility: Suitable for a wide range of applications, from construction to industrial machinery.

• Regularly check bolts for tightness, particularly in high-vibration environments.
• Keep bolts clean to avoid the accumulation of corrosive substances.
• For extreme environments, consider applying a protective coating to further enhance the bolt's longevity.

A2-70 is an austenitic stainless steel grade typically based on 304 or 304L material. It has a minimum tensile strength of 700 MPa and a yield strength of 450 MPa, with an elongation of at least 40%. This grade is characterized by its excellent corrosion resistance, which is attributed to its high chromium content.

A4 grade, on the other hand, is typically made from 316L stainless steel, which is known for its superior corrosion resistance, particularly in marine and chemical environments. This grade has a minimum tensile strength of 700 MPa and a yield strength of around 207 MPa.
