“I am looking for an alternative to plugging tapped holes prior to powder coating and eliminating this step. I have considered tapping after coating, using self tapping screws and ‘over sizing’ the tapped hole to compensate for the coating thickness. Each of these has their own inherent problems. What is the common practice in the industry? Thanks.”

“You have mentioned both corrective actions for tapped holes. Masking with plugs or post machining after coating. There are no other alternatives that can be employed on a production basis.”
