The Carriage Bolt Cone Nut Combination Screw achieves installation efficiency and connection strength through deep optimization of structure and materials. The wide load-bearing surface design of the cone nut increases the contact area between the bolt and nut, thereby increasing strength. Jinghong's advantage in providing customized carriage bolts and cone nuts lies in its unique cone locking structure.
The semi-circular head design of the carriage bolts combines aesthetics and practicality, with a smooth and angular head. At the same time, the bolts are forged from high-strength alloy steel and have undergone anti-corrosion treatments such as Dacromet and hot-dip galvanizing on the surface, resulting in high tensile strength and no corrosion after over 1000 hours of salt spray testing. When used in combination with a conical nut, the inner wall of the conical nut forms a precise wedge-shaped fit with the bolt head. When the nut is locked, the conical surface generates bidirectional pressure, which precisely engages the bolt head and connecting piece, forming a self-locking effect.
Strict quality monitoring is carried out at every stage of the production process to ensure that the products meet high-quality standards. From cutting and forming of raw materials to heat treatment, surface treatment, etc., every step must be carefully operated and rigorously inspected. The design of carriage bolts makes it very convenient to use tools for installation and disassembly, whether it is manual operation or mechanized installation, it can be quickly completed.
