It uses a small pilot hole that causes the sheet metal to extrude forming more thread engagement and more resistance to stripping the sheet metal. A common method of self locating parts in machine assemblies is to use dowel pins which can then either be used strictly as a locating feature to hold parts in the correct place during assembly with screws or can be used on their own for press fit assembly. The benefits of self location aren t just for welded or sheet metal parts. Which is best depends on the material its thickness and the application requirements.
