The unique design of these Non Removable Two-Piece Plastic Rivets provides a controlled grip range through a built-in stop on the rivet body. These rivets can be used with most standard pop-rivet setting tools. The pin breaks off when it is even with the head, providing a finished appearance on both sides of a panel. Rivets listed on this page are made from Super Tough UV Stabilized Nylon and Acetal. Additional materials and colors are also available directly through EFC International (see below).
