Blind Rivets - Dome Triform

What are Triform Blind Rivets?

A Triform Blind Rivet has a body that on application separates into three parts on the blind side of the rivet, making it ideal for use where the materials being fastened are soft or fragile. They are commonly used when working with timber, soft metals, insulation, plasterboard and various plastics.

Blind Rivets are so-called because they can be used to fasten two items together without the operator needing to have access to the rear surface (the blind side) of the items being joined.

The rivet has a stem called a mandrel. The mandrel is inserted into a rivet gun and the protruding body of the rivet is then pushed into the hole and through the materials that are being fastened. The mandrel is then pulled back, forcing the sides of the rivet to expand outwards. When the rivet can expand no further the mandrel snaps off, leaving a neat and tidy finish on both surfaces.

 

About our Blind Rivet range:

We have all types of Pop Rivets available in various designs - Dome Head, Countersunk, Large Flange, Sealed, and Triform – each in a range of finishes.

  • Dome Rivets are the most common, this option leaves a slightly raised dome finish.
  • A Countersunk Rivet fits flush to the surface in a countersunk hole.
  • Large Flange Rivets spread the load over a greater area and Sealed Rivets leave a sealed closed-end finish.
  • A Triform Rivet splits the body into three parts, which reduces the likelihood of damage to the material, making this the perfect option for soft metal sheets.

We have Stainless Steel Blind Rivets available, as well as in other materials like normal steel, and two types of aluminium (standard and black-painted finish) which comes in two sizes.
