Hex Head Cap Screw Aluminum 2024 T4 205 Finish

Aluminum 2024-T4 Hex Head Cap Screw with a 205 Finish is a high-performance fastener distinguished by its distinctive yellow-green chromate conversion coating.  This specific finish, often referred to simply as "205 Finish," provides an additional layer of chemical protection against corrosion, which is vital since the 2024 alloy’s high copper content makes it naturally susceptible to oxidation. It is widely used in aerospace and military applications where both high fatigue resistance and a recognizable identification color for specific assembly zones are required.

The 205 finish is primarily functional, designed to enhance the longevity of the fastener in atmospheric environments while maintaining the alloy's structural integrity.
