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. |
