What size would the hole be in the sheet metal? I'm using a 4.2 mm dia. screw?What does a conical depression hole in sheet metal look like? Is it for a self tapping screw?
Conical= cone shaped
A self tapping screw could produce this. Of you have self tapping screws, you will create a hole. If you need to drill a hole, slightly smaller than the screw size.
