This brass Cutler’s Rivet has a head diameter of 5/16″, shank length 1/2″, and a total compressed length of 5/8″, in the most compressed state. The least compressed state would be 15/16″. The length of each piece is 1/2″.
This rivet is known as a Cutler’s rivet, a Cutlery rivet, a compression rivet, or a squeeze type rivet. It is a relatively easy to install compression-type rivet which consists of one male and one female half. Push them together at least 1/8″ for a permanent bond. Please take into consideration that the female half expands when the rivet is compressed. Use only a vise or arbor press, do not use a hammer.
