The CR3213-5-2 Lock Rivet is a high-strength blind rivet designed for structural aircraft applications where access is limited to one side of the assembly. It is part of Cherry Aerospace’s mechanically locked rivet family, providing reliable and vibration-resistant fastening.

This rivet features an internal locking mechanism that secures the mandrel in place after installation, ensuring consistent clamp force and enhanced structural integrity compared to standard blind rivets.

Supplied as a pack of 100 pieces, these rivets are widely used in airframe assembly and repair operations.

Its primary functions include:

Providing strong, vibration-resistant fastening in structural assemblies
Allowing installation from one side (blind installation)
Maintaining secure clamp load with mechanical locking feature

Lock rivets like the CR3213-5-2 are essential in modern aircraft construction and maintenance, offering a dependable solution for high-strength joints where traditional solid riveting is not feasible.
