Aluminium Blind Rivet

A blind rivet is a fastening element for joining metal sheets. It is used when there is no access to the back side of the structure being fastened. Installation is performed only with a special tool — a pneumatic rivet gun; a hammer is not suitable for this.

Product features

The rivet is shaped like a mushroom — a cylinder with a cap at the end. The cylinder is hollow, with a long mandrel inserted inside. During installation, the mandrel breaks off and is removed from the structure — hence the name “blind” rivet.

The rivet body is usually made of aluminium, while the mandrel is made of a stronger material, such as steel.

The most common sizes: diameter 3.2–6.4 mm, rivet length 5.8–25.2 mm, mandrel length — 27 mm.

Application and installation rules

Rivets are used to fasten thin sheet materials across various fields. The main requirement is that access is open from only one side of the structure.

Installation procedure: first a hole is drilled, then the rivet is inserted into it cylinder-first. After that, pressure is applied to the mandrel with the pneumatic tool. Under the load, the cylinder flattens out on the back side, and the mandrel breaks off — it only remains to pull it out and discard it.
