2 piece mate rivets are non-structural fastening rivets for extra-long grip applications. To install 2 piece rivets, access to both sides of the work piece is required. The tubular component is inserted from one side, and the rivet itself is inserted from the opposite side. The fastener is set with a rivet tool, which expands the rivet inside the tubular component to create a tight, secure grip without damaging the host material. Two-piece rivets do not require close tolerance holes for proper installation.
