A rivet installation verification stick is a tool utilized to ensure proper setting of blind rivets, often referred to as pop rivets. This gauge helps determine if the rivet has been correctly installed by checking the protrusion of the rivet mandrel relative to the rivet head. A correctly set rivet exhibits a specific mandrel break-off point and a flush or slightly recessed mandrel end.
The use of this instrument guarantees structural integrity in fastened assemblies. By consistently verifying rivet installation, potential failures due to improper setting can be avoided. Its historical context emerges from industries demanding reliable fastening solutions, particularly where visual inspection alone is insufficient to confirm a secure bond.
