Hexagonal bolts are the most widely used universal fastening standard components, consisting of a hexagonal head and a threaded rod body, combined with nuts, flat washers, and spring washers. They rely on threaded engagement to complete the locking and fixing of various components. With the characteristics of easy disassembly, uniform force distribution, and strong load-bearing capacity, they have become the core connecting components in the fields of mechanical manufacturing and infrastructure engineering. The products cover a series of hexagonal bolts, including regular bolts, enlarged hexagonal bolts, half tooth bolts, full tooth bolts, fine tooth hexagonal bolts, high-strength quenched and tempered hexagonal bolts, etc. They comply with general standards such as national standards, German standards, and American standards, and have specifications covering full-size threads. The raw materials for the product are selected from high-quality low-carbon carbon steel, medium carbon alloy structural steel, 304/316 stainless steel, etc. Ordinary carbon steel bolts are formed using the cold heading integrated molding process, with neat and burr free molding; Grade 8.8, 10.9, and 12.9 high-strength hexagonal bolts undergo quenching and tempering heat treatment to achieve high tensile strength and excellent fatigue resistance. They are not easily stretched or broken under long-term vibration and heavy load pressure conditions. The thread is processed using high-precision rolling technology, with a full and clear tooth profile, tight and smooth meshing, and repeated disassembly and assembly to prevent slipping and thread detachment. Surface anti-corrosion treatment can be carried out using various processes such as blackening, electroplating, hot-dip galvanizing, Dacromet, zinc nickel alloy, stainless steel mirror polishing, etc. The coating has strong adhesion and can effectively resist water vapor, salt spray, acid and alkali corrosion. It is suitable for different working environments such as indoor drying, outdoor, coastal, chemical, etc. All finished products undergo multiple quality inspections such as thread testing, hardness testing, tensile load testing, salt spray corrosion resistance testing, etc., with standard dimensional tolerances and excellent interchangeability. Widely applicable to assembly scenarios in industries such as steel structure factories, engineering machinery, wind and photovoltaic brackets, new energy storage equipment, rail transit, machine tool molds, pipeline valves, municipal bridges, furniture and hardware, automotive parts, etc. Regular standard specifications are available in stock, and customized extended, thickened, fine toothed, special length, non-standard irregular hexagonal bolts can be made according to drawings and requirements. The assembly is stable and reliable, greatly improving the overall safety of equipment and engineering structures.
