ABOUT THIS BUTTON HEAD SCREWS
Upgrading from black oxide to a zinc-nickel coating offers a leap in corrosion resistance. While black oxide provides minimal protection against rust, zinc-nickel can withstand over 400 hours in a neutral salt spray test, offering superior performance. Additionally, zinc-nickel boasts excellent heat resistance (withstanding over 200°C) and better abrasion resistance. This makes it a far more robust and durable choice for demanding applications in harsh environments.
