What Are Coated Fasteners?
Coated fasteners are threaded components treated with a protective surface layer to enhance resistance against rust, wear, chemicals, moisture, and extreme temperatures. The coating not only extends the service life of the fastener but also reduces friction, improves aesthetic appeal, and ensures reliable performance under tough operating conditions.
