Product Description

Hex Bolt

Hexagonal head bolts, as one of the most widely used fasteners, play a key role in many fields due to their high load-bearing capacity, easy installation and disassembly, and adaptability to various tools.

Buildings and infrastructure : It's used for connecting and anchoring large components such as steel structure factories, bridges, towers, and photovoltaic brackets. High anti-corrosion surface treatments such as hot-dip galvanizing are often used to cope with long-term outdoor exposure environments. Mechanical and equipment manufacturing : It's widely used for connecting frames, bases, and transmission components of machine tools, engineering machinery, agricultural and mining equipment. High strength grade bolts (such as 8.8 and 10.9) can effectively withstand vibration and impact loads. Automotive, rail transit, and aerospace : It's used for fastening critical load-bearing parts in automotive engines, chassis, high-speed rail vehicles, and aircraft structures. These applications have extremely high requirements for the strength, fatigue performance, and reliability of bolts.

Energy and chemical equipment : It's suitable for sealed connections of pressure vessels, pipeline flanges, wind turbine towers, and other equipment. Stainless steel or special alloy materials are often used, combined with hot-dip galvanizing, Dacromet and other anti-corrosion treatments to ensure long-term safety in high temperature, humidity or corrosive media.

 General equipment and daily maintenance : It have become common choices in various equipment assembly, cabinet fixation, pipeline support, and daily maintenance due to their complete specifications, unified standards, and easy procurement
