Structural Bolts are a specialized heavy type of hex bolt intended for use in large structures, such as buildings and bridges. This bolt is designed to withstand the loads of steel-to-steel structural connections. They contain a flat, washer-faced bearing surface and a chamfered thread point. Plain finish, or bare metal, may or may not have a coating of light oil to resist corrosion.
Galvanizing process: A layer of zinc is plated on the surface of the product for surface treatment such as appearance and rust prevention.
Fine workmanship: Standard external hexagon, smooth surface, uniform force, easy to slip when rotating.
Fine thread: the screw mouth is deep, the pitch is uniform, the surface is smooth, and there is no burr.
Fasteners are widely used in various industries, including energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, mold, hydraulic industry, etc. various fasteners can be seen in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies, which are the most widely used mechanical foundation parts.
It is characterized by a wide variety of specifications, different performance uses, and standardization, seriation,
generalization of the degree is also very high.
