This document does not specify requirements for the condition of the basis metal surface prior to zinc electroplating. However, defects present on the basis metal surface may adversely affect the appearance and performance of the coating.

The thickness of the coating that can be applied to threaded components may be limited by dimensional requirements, including the thread class or fit.
