Product Details
Product image
Flange bolts are mechanical fasteners composed of hexagonal heads, flange plates and threaded rods. They need to be used in conjunction with nuts and are widely applied in fields such as automobiles, Bridges and heavy machinery.
Structure and composition
The core structure of a flange bolt consists of three parts: hexagonal head (providing the force-bearing surface for tightening with a wrench), flange plate (integrated gasket structure, increasing the contact area to distribute pressure), and threaded rod (a cylinder with external threads). Its integrated design avoids the trouble of adding additional gaskets to ordinary bolts and enhances the anti-loosening performance.

features
Youdaoplaceholder0 High-strength connection : The flange design makes the ratio of the support area to the stress area larger, which can withstand higher preload force and is suitable for scenarios with frequent vibration.
Youdaoplaceholder0 anti-loosening performance : Some models of flange plates have toothed patterns or are combined with rubber sealing rings (such as silicone rubber skirts) to form a double-layer anti-loosening barrier.
Youdaoplaceholder0 Corrosion resistance : Surface treatments include galvanization, dacromet coating, etc. Some are made of alloy steel materials (such as SCM435 chromium-molybdenum steel) to enhance durability.
application fields
Youdaoplaceholder0 automotive industry : connection of engines, steering systems and body panels.
Youdaoplaceholder0 Heavy machinery : reamed hole connections for equipment such as excavators and cranes.
Youdaoplaceholder0 infrastructure projects : high-strength fastening of highway/railway Bridges and building steel structures.
