Our company specializes in the production of hexagon head bolts, which are widely used in mechanical equipment, hardware brackets, home appliance assembly and general industrial scenarios, providing stable and reliable fastening solutions for customers.

This series of bolts are made of high-quality carbon steel wire to meet the strength and fastening requirements of conventional industrial applications. The head adopts a standard hexagon structure, which is compatible with common wrenches and socket tools for easy on-site installation and later maintenance. The integrated flange version has a larger contact area with uniform force, reducing the need for additional gaskets to improve assembly efficiency and avoid surface damage to fastened objects. The threads adopt a metric coarse thread design with clear, regular patterns free of burrs or broken teeth, ensuring tight fit and preventing loosening or slipping after assembly. The surface is treated with environmentally friendly galvanizing, featuring a uniform and dense coating with basic anti-rust and anti-corrosion properties, suitable for conventional indoor use and resistant to oxidation and rust over long-term use.

In the production process, we implement full-process control over raw materials, cold heading forming, tapping, heat treatment and finished product delivery. When raw materials enter the factory, their composition and basic performance are tested to ensure product quality from the source. In the cold heading forming process, we focus on controlling the size of the bolt head and the straightness of the shank to avoid cracking and deformation. The tapping process uses automated equipment to ensure consistent thread accuracy without defects. At the finished product stage, each batch undergoes full dimensional inspection, torque testing and anti-rust sampling inspection to ensure the products meet usage standards and prevent unqualified products from leaving the factory.
