Bronze Pins

Bronze Pins offer superior strength and wear resistance compared to brass or copper. They are ideal for moving parts, pivot points, and marine environments where durability and anti-corrosion properties are paramount. We typically use Phosphor Bronze or Aluminum Bronze for these applications. Our pins are precision ground to fit tight tolerances, ensuring smooth operation in hinges, shackles, and actuators. We can also provide them with grease grooves for lubrication.
