How a rivet works

A rivet clamps layers between two heads after its plain end is swollen in the hole.

When the purchase is complete, return to the original window. It will refresh.

From the opening

A rivet is a metal pin passed through holes in two or more layers, then swollen at the plain end until a second head forms. The two heads clamp the layers, and the shank fills the hole so the joint can carry a sideways load. The opening covers tail upset into a second head, shank swells and fills the hole, and heads clamp and shank shears.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
