Important Materials

The materials used in your boat trailer lock greatly affect its strength and longevity. Here are some common and important ones:

  • Hardened Steel: This is a very strong metal. It resists cutting and drilling. Many high-security locks use hardened steel.
  • Stainless Steel: This metal is excellent for resisting rust and corrosion. It is a good choice for locks that will be exposed to the elements, especially near saltwater.
  • Brass: While not as strong as steel, brass can be used for internal lock components. It is also resistant to corrosion.
