Rivet

A rivet is a mechanical fastener consisting of a smooth cylindrical shaft with heads on either end, the second one formed in position. The heads are somewhat larger than the diameter of the hole into which the rivet has been inserted. Generally one head is factory formed. The other is formed by clenching metal after the rivet has been inserted.

This can be done with a solid rivet, either by applying force by holding up the head end with a dolly and clenching the other with a manual or a pneumatic hammer or with a die over the end to be clenched, by squeezing rivet and work together with a press. Portable presses for the job are usually pneumatic.

Blind rivets are tubular and are supplied with a mandrel through the centre. The rivet assembly is inserted into a hole drilled through the parts to be joined and a specially designed tool used to draw the mandrel into the rivet. This expands the blind end of the rivet and the mandrel snaps. This gives the rivets their common name of pop rivet. (See blind rivet)
