Helpful in applications with minimal access to the opposite side. Requirement handheld tools are sufficient. Specialized tooling required for installation. While basic threaded bolts will loosen when subjected to heavy vibration, it can be avoided by securing with Nord-Lock washers. Will not turn loose due to the fact that of vibration. Can be eliminated quickly and quickly using standard tools, and parts can be reused.

It looks rather like a nail. To set up one, a jaw on a setting tool grips the mandrel, pulls it into the rivet body through a drilled or punched victory or more layers of material. The mandrel head broadens the walls of the rivet outside, pushing them securely into the walls of the hole while forming a firmly clinched load-bearing location on the opposite side of the material.

Rivet producers put grooves on some mandrels to damage them, in essence predetermining the area where tension will break them. Some mandrels also have a mechanical lock that snaps into location, plugs the opening in the rivet shell, and captures the remaining portion of mandrel inside the sleeve.

If necessary, rivets with big heads (a minimum of 50% larger than the hole) can be used to spread the load further.

As a guideline, mandrel heads should be big enough to spread the load however not so large regarding waste material and include unnecessary weight. Blind rivets can make up for irregular holes, as long as they are within 0. 004 in. of the rivets' growth variety.
