It is essential to use the correct tapping technique and tools to ensure successful threading in a 3mm iron or stainless steel plate.

For 3mm thickness stainless steel specifically, tapping can be feasible with proper tools and techniques. 

However, considering the material's hardness, it is advisable to use high-quality taps and cutting fluids to facilitate the process. If tapping is challenging or not preferred, alternatives like self-clinching nuts (PEM Nuts) or other methods to create internal threads can be considered for the 3mm stainless steel plate.

When creating threads in metal plates, precision, correct tool selection, and technique are crucial to ensure the durability and strength of the threaded connection.
