China ASTM A307 GrB Manufacturer, Supplier, Factory

Hex Flange Screw Metric Without Serration, our bolts offer exceptional performance and reliability in even the most demanding environments. The hexagon flange design of these bolts provides a larger bearing surface and a more secure fastening, ensuring that your equipment remains safe and secured at all times. Additionally, our bolts are designed with a metric thread which is perfect for use in a wide range of industrial and engineering applications.

ANSI A490 Balck Heavy Hex Bolts are specifically designed for use with heavy hex nuts in the connection of structural members (as opposed to tapped holes). ANSI A490 Balck Heavy Hex Bolts are strong heavy-duty bolts that are typically used for creating structures through steel to steel structural connections such as buildings and bridges. A grade 8 bolt would be one that meets ASTM A490 standards. The high quality steel used to create ANSI A490 Balck Heavy Hex Bolts are designed for strength and durability, allowing ANSI A490 Balck Heavy Hex Bolts to conform to ASTM A325. ANSI A490 Balck Heavy Hex Bolts are often applied alongside structural nuts and washers to metal beams and girders.

ASTM A307 Grade B Carbon Steel Threaded Rod These studs are made from premium-grade carbon steel that offers exceptional strength and durability. ASTM A307 Grade B Carbon Steel Threaded Rod have a thick coating for excellent corrosion resistance. (To ensure compatibility, use these screws with hot-dipped galvanized steel nuts.) They come in a range of lengths and diameters to suit your requirements, and their fully threaded design ensures a secure hold for any application.

The step design of our ISO8677 Round Head Square Neck Bolt also adds to its versatility. ISO8677 Round Head Square Neck Bolt has stepped threads that increase the grip of the bolt, which is particularly useful when bolting through soft materials such as wood. Whether you need to fasten two or more objects of varying thicknesses or even hang a picture on the wall, ISO8677 Round Head Square Neck Bolt is up to the task. The combination of its knurl round head design, double steel structure, and step design make it versatile, practical, and aesthetically pleasing, making it an essential addition to any toolbox.

ANSI B18.2.2 Square Nut are Made with top-quality materials, these nuts are known for their durability, strength, and corrosion resistance. ANSI B18.2.2 Square Nut are designed to last. The high-quality steel construction provides excellent tensile strength, meaning they can handle high load capacities without deforming or breaking. Galvanized Carbon steel is also resistant to corrosion, so ANSI B18.2.2 Square Nut stand up well even in wet and humid environments.

Large Hex Flange Nut provide a secure and tight fit, while also preventing the nut from loosening due to vibration. This is especially important in industries where machinery and other heavy equipment are used, as any loosening of fittings can cause dangerous and costly consequences. The flange of Large Hex Flange Nut acts as a washer, providing additional support while preventing the nut from embedding itself into the surface of the material being fastened. This greatly reduces the risk of damage to the structure, as well as providing a more aesthetically pleasing finish.
