Heavy-Duty Rivet

Heavy-duty rivets are a type of fastener designed for increased loads.

They are used to join sheet metals. Such joints are distinguished by increased impact resistance, vibration resistance, and, when needed, sealing.

The most common type of heavy-duty rivets is the blind rivet. It consists of a small hollow cylinder with a head at one end, with a long mandrel threaded through it. The advantage of this design is that these rivets can be used even when only one side of the structure being joined is accessible.

Product features

Heavy-duty rivets are most often made of stainless steel. This material is strong enough to withstand any loads.

The most popular sizes of these fasteners are diameter 2.4–6.4 millimeters, length 3.2–12.3 millimeters. The mandrel length is the same for all sizes — 27 millimeters.

Application and installation features

Heavy-duty rivets are used, for example, in the manufacture of special vehicles and agricultural machinery. They are also used to join parts of various machines subject to constant vibration.

A pneumatic rivet gun is used for installation. The rivet is inserted into a pre-drilled hole with the mandrel facing up. Through this mandrel, the gun transfers load to the other end of the cylinder and flattens it. The mandrel subsequently breaks off and is discarded.
