Industrial 1/2-20 12-Point Self-Locking Flange Nut Dry Film Lubricated 500F Flange Nut

This 1/2-20 UNC, 12-point self-locking flange nut with a dry-film lubricant is designed for high-vibration, high-temperature assemblies where a dependable, repeatable preload matters. The built-in flange acts as an integral washer to distribute clamping load and simplify installation, while the 12-point external drive supports high-torque engagement in tight or awkward spaces without slippage. Manufactured from alloy steel and cadmium-plated for corrosion resistance, this nut carries a dry-film lubrication that minimizes friction and galling across multiple tightening cycles and helps maintain consistent torque values. The prevailing-torque locking action resists loosening under vibration, making it a suitable choice for aerospace, defense, and industrial equipment that operate in demanding environments. In systems that follow similar dry-film-lubed, self-locking flange-nut specs, the rated operating temperature is around 450°F (232°C), enabling use in high-temperature applications without compromising lock integrity. Use with standard 1/2-inch bolts to achieve secure fastening where a flange provides added stability and a low-profile, easy-to-install locking solution.
