Cadmium plating KATO Tangless and tanged CoilThread inserts significantly increases corrosion protection. Cadmium plating is primarily used to protect against corrosion, but like Molybdenum Disulfide, helps decrease the coefficient of friction between the insert and the bolt to minimize galling.

Cadmium is applied in accordance with AMS-QQ-P-416. The identification colors vary depending on the type of inserts (locking vs. free-running). A supplemental Olive Drab to Dark Brown chromate is required to identify Locking Inserts. Gold to Yellow chromate is required to identify Free-Running Inserts (NASM8846).

Cadmium plating is meant to show no evidence of corrosion when exposed to a continuous salt spray test (96 hour ASTM B 117 test in accordance with NASM1312-1).

The suffix “Y” is added to KATO part numbers (ex. 2TLC-02C-0086Y) to signify the application of Cadmium.
