The 1/2-13X1-1/4 Grade 8 Hex Flange Bolt is crafted from high-strength quenched and tempered steel, making it suitable for demanding structural applications. This material provides excellent tensile strength and hardness, essential for maintaining joint integrity under high-stress conditions. The Grade 8 rating ensures that the bolt can handle significant clamp loads, making it a reliable choice for applications where long-term stability is critical.
Featuring a phosphate finish, this bolt is enhanced with an oil coating, which aids in reducing friction during installation and assembly. While the phosphate coating offers limited corrosion protection, it is primarily beneficial for its anti-galling properties, ensuring smooth operation in pre-torqued joints. The hex flange design provides a larger bearing surface, distributing clamping force more evenly and reducing the risk of loosening under vibration.
Equipped with a coarse thread pitch, this bolt allows for quicker assembly and disassembly, saving time in applications that require frequent adjustments or maintenance. Its robust construction and design make it an appropriate choice for environments where mechanical loads are prevalent, though it should be noted that the phosphate finish may not withstand prolonged exposure to harsh or corrosive environments.
