Sariv Cap (Sealed End ) Blind Rivets pg219cc
	Threaded Head Blind Rivets Steel Head / Steel Mandrel Metric Thread Closed-end blind rivets are called often referred to as CAP RIVETS . They should be used when riveting should be airtight or watertight. The CAP blind rivet itself is always tight. A quick glance at the rivet is sufficient to understand the reason. However, will the riveting solution be always as tight as the rivet itself? Closed end rivets are made of a fairly hard aluminium alloy. The hardness of the shaft material however produces only a low hole filling capability. Consequently, hole drilling accuracy becomes a very serious matter indeed. Otherwise, the riveting will not be tight enough to prevent water flowing, not through, but around the set rivet.
