Designed for the most demanding structural applications, this hex heavy bolt is made from carbon steel grade 12.9, which provides exceptional tensile strength and durability. The M16 size with a 7/16-inch thread ensures a strong and secure fit in large-scale constructions, such as steel framing, bridges, or machinery assembly.

The zinc-plated finish provides additional corrosion resistance, making the bolt ideal for environments exposed to moisture, chemicals, or other harsh elements. The bolt meets ASTM A193 and A194 standards, which ensures it can endure extreme loads and stresses while maintaining high performance. Its robust construction makes it a top choice for heavy machinery, structural supports, and other critical infrastructure projects.

Manufacturing materials: Ordinary bolts are generally made of ordinary steel, while high-strength bolts are made of high-quality steel, and special treatment is used to improve their strength and durability.

Manufacturing process: The manufacturing process of ordinary bolts is relatively simple, while high-strength bolts need to go through a number of more complex heat treatment and production processes to ensure their high strength and stability.

Occasions for use: Ordinary bolts are mainly used in ordinary structural connections, such as wooden structures or light steel structures. High-strength bolts are mainly used in heavy industry and high-rise building load-bearing structure connection, such as bridges, large industrial plants and so on.

Hex bolts are indispensable in various industrial and consumer applications due to their strength, versatility, and ease of use. They provide reliable and durable fastening solutions across multiple sectors.
