DIN 1477 Grooved Rivet with Countersunk Head

The grooved rivet with countersunk head is manufactured in accordance with the requirements of the German standard DIN 1477 from carbon and stainless steel. Carbon-steel items are supplied with zinc or nickel plating, or without any coating at all. For special applications, rivets made of aluminium, copper, brass and bronze are also available.

The rivet is a cylinder with chamfers on one side, smoothly transitioning into a countersunk head on the other. The outer surface of the working cylinder has longitudinal grooves. In many respects, the DIN 1477 rivet corresponds to ISO 8747 fasteners, but calling them full equivalents would be a considerable stretch. It is safer to purchase the fastener specified in the assembly drawing, or, for a replacement, to obtain a specialist’s recommendation.

Where and how grooved rivets are used

Drive-in rivets, which include the countersunk rivet with longitudinal grooves, are used in most branches of mechanical engineering, shipbuilding, aircraft manufacturing, construction, and instrument engineering.

The grooves on the fastener shank promote a stronger and more reliable grip with the materials being joined. That is why DIN 1477 rivets are especially effective when used with a base material of low density. Riveting is carried out in the following order:

• first, a hole is drilled in the workpiece, with a diameter slightly smaller than the rivet size;
• the rivet is inserted into the hole and driven in with an ordinary hammer until the head is fully seated;
• on the opposite side, the tip of the shank is flattened with light blows of the same hammer to make the joint stronger.

The countersunk head of the DIN 1477 rivet with longitudinal grooves makes the fastener less noticeable and gives a tighter fit at the joint with the base material. This makes it possible to create an even, smooth surface that can be painted or coated with other protective finishes without obstruction.
