Precision Friction Control and Corrosion Protection for Fasteners
With billions of fasteners protected worldwide, the 500 Series has become a benchmark for fastener coating performance and continues to evolve to support PFAS-free and water-based coating solutions.
The ÁñÁ«appµ¼º½Èë¿Ú 500 Series is the company’s flagship family of high-performance fastener coating systems, engineered to deliver reliable corrosion protection and precise friction control in bolted joints. Designed for automotive and industrial applications, the 500 Series protects threaded fasteners, clamps, small stampings, and engineered components, supporting long-term durability across global platforms and demanding production environments.
Developed with a deep understanding of fastener behavior during assembly and service, ÁñÁ«appµ¼º½Èë¿Ú 500 Series coatings integrate lubricants directly into the coating system and tightly control friction to achieve consistent clamp load and repeatable joint performance. Zinc-rich basecoats combined with engineered topcoats provide durable corrosion protection while enabling stable torque-tension relationships across millions of assemblies.
The platform includes solvent- and water-reducible basecoats and topcoats, as well as water-based topcoat technologies, supporting evolving environmental and regulatory requirements while maintaining proven performance.

Proven Where It Matters
The origins of the 500 Series trace back to early automotive fastener coating programs developed for highly demanding OEM performance applications. From those early systems through the industry-wide transition to chrome-free coatings, ÁñÁ«appµ¼º½Èë¿Ú fastener technologies have continually evolved to meet rising regulatory and durability requirements.
Today, the ÁñÁ«appµ¼º½Èë¿Ú 500 Series is used globally across:
- Passenger vehicles, trucks, and SUVs
- Electric and hybrid platforms
- Agricultural, construction, and off-highway equipment
- Wind, solar, and energy infrastructure
- Industrial fasteners exposed to harsh chemical and outdoor environments
What the 500 Series Delivers
Flexible System Architecture
- The ÁñÁ«appµ¼º½Èë¿Ú 500 Series supports multiple coating architectures to match the corrosion, friction, and assembly requirements of different fastener applications:
- Single-Layer Systems – Zinc-rich coatings with integrated friction modification built into the coating, providing simplified processing and consistent torque-tension performance.
- Two-Layer Systems – Zinc-rich basecoat combined with a lubricated topcoat engineered to control friction and enhance corrosion performance.
- Multi-Layer Systems – Advanced coating stacks incorporating functional topcoats, sealers, or specialty layers for demanding environments requiring enhanced durability, appearance, or chemical resistance.
