3/8 1/2 ASTM A193 A194 Hex Heavy Duty Bolt Nut Washer B7 B8 GR 8 8M ASME B16.5

Product Description:
The 1/4 and 5/16 hex heavy-duty metal cap bolts made from ASTM A193 and A194 materials are designed for high-strength applications, particularly in pressure vessels, boilers, and flanged joints. These bolts are made from high-quality B8 and B8T stainless steel, which ensures excellent mechanical properties and resistance to high temperatures and corrosive environments.
Features:
• High-Temperature Resistance: ASTM A193 B8 and B8T materials are designed to perform in high-temperature environments, making these bolts ideal for applications in power plants and chemical processing industries.
• Heavy-Duty Construction: These bolts are designed to handle high-pressure and high-stress applications, ensuring secure fastening even in demanding environments.
• Compliant with ASME Standards: These bolts meet ASME B16.5 standards, making them reliable for use in various industrial applications.
Advantages:
• Exceptional Strength: These bolts can handle high mechanical stresses and pressure, making them ideal for critical applications in industries such as petrochemical and oil and gas.
• Corrosion Resistance: The B8 and B8T materials provide resistance to oxidation and corrosion, ensuring a long lifespan even in extreme conditions.
• Ease of Use: The hexagonal shape and heavy-duty design allow for easy installation with standard wrenches.
Maintenance Tips:
• Regularly inspect the bolts for signs of wear or deformation, especially under high-stress conditions.
• Lubricate bolts to reduce friction during tightening and ensure a secure connection.
• In extremely hot or corrosive environments, replace bolts as necessary to maintain structural integrity.
Applications
1, A193-B7/A194-2H is warm with alloy steel bolt material bolts and nuts;
2, bolt: mechanical parts, with a nut cylindrical with threaded fasteners. By the head and screw (cylinder with external threads) two parts of a class of fasteners, need to cooperate with the nut, used to fasten the connection of two parts with through-hole;
3, this form of connection called bolt connection. Such as the nut from the bolt screwed down, and can make the two parts separate, so the bolt connection is a removable connection.
Screws: the use of the object's bevelled circular rotation and friction of physics and mathematical principles, step by step to fasten the tool of the machine parts.
Bolt: Mechanical parts, with a nut with a cylindrical threaded fastener. By the head and screw (cylinder with external threads) two parts of a class of fasteners, need to cooperate with the nut, used to fasten the connection of two parts with a through hole.
