Identify the type of rivet head usually used for boiler plate riveting:
The snap heads are usually employed for structural work and machine riveting. The counter sunk heads are mainly used for ship building where flat surfaces are necessary. The conical heads (also known as conidal heads) are mainly used in case of hand hammering. The pan heads have maximum strength, but these are difficult to shape.
