Cylindrical Rivet Nut

The cylindrical rivet nut is a fastener of a distinctive shape designed for joining thin-sheet materials. An internal thread is formed at the joint.

A rivet nut consists of three parts:

• the top flange head: flat, countersunk, raised countersunk, or reduced;
• the central deformable part;
• the reverse side with internal thread. The lower end can be closed or have a through hole.

Product features

Rivet nuts are an alternative to welded fasteners. Their use eliminates welding and painting from the process. This is an inexpensive and durable fastener used for high-volume work, for example in industrial production.

Application, mounting and use rules

Rivet nuts are used in machine building and the automotive industry, in furniture assembly, and in instrument manufacturing. Installation is performed as single-sided mounting with a rivet nut tool, in the following sequence:

• a hole is made at the mounting location;
• when using nuts with a countersunk head, the hole is countersunk;
• the rivet nut is screwed onto the threaded tip of the tool and inserted into the hole;
• after the tool is activated, the deformable part of the fastener flattens, pressing the sheets against the head.
