Cadmium Plating

 Iridescent yellow Provides high corrosion resistance and lubrication to prevent galling. Suitable up to 250°C
Zinc Plating
 White

Provides corrosion resistance as an alternative to Cadmium.
Silver Plating Silver white To reduce galling of threads at high temperatures.
Cadmium Plate &
Olive Drab		 Olive Drab As specified on US military specs such as NASM21209.
Dry Film Lubricated Grey Additional lubrication in high friction applications. Recommended for use with Screw Grip inserts.
BaerCoilGuard Glossy Black Prevents galvanic corrosion between insert and patent material. Eliminates the need for zinc primers. Improves installation productivity.
