The washer is often called a lock washer, star lock washer or clamping washer or ring.

The threadless bolt is often called a pin.

One name it goes by is a PEM pin.

In addition to the various washer names given by Solar Mike, it might also be called various forms of push-on retaining clips/rings (whereas a normal retaining clip expects a groove).
