The 1/2-13X4 Grade 8 Hex Flange Bolt is crafted from high-strength steel, delivering excellent tensile strength and hardness. Grade 8 steel is quenched and tempered, making it suitable for demanding structural applications where maintaining joint integrity is crucial. This material choice provides the bolt with the ability to withstand significant loads without deformation, ensuring reliable performance in critical assemblies.
Featuring a phosphate finish, this bolt enhances lubricity and reduces galling, making it easier to handle and assemble. The phosphate coating also offers short-term corrosion protection, which is beneficial during transportation and assembly. For applications requiring quick assembly and disassembly, the coarse thread pitch allows for efficient installation while maintaining strong holding power.
The hex flange design adds an integrated washer surface, distributing the load over a larger area and minimizing the risk of bolt loosening under vibration. This design feature is particularly advantageous in mechanical assemblies where maintaining consistent clamping force is essential.
