How to Measure a Blind Rivet

Dome Head and Large Flange Head – the rivet body length (L) is always measured from under the head to the end of the body.

D = body diameter

L = body length

dk = rivet head diameter

K = rivet head thickness

dm = mandrel diameter

L2= minimum mandrel length

Countersunk Head – the rivet body length (L) is always measured from the top of the head to the end of the body.

D = body diameter

L = body length

dk = rivet head diameter

K = rivet head thickness

dm = mandrel diameter

L2= minimum mandrel length

How to Install a Blind Rivet

  1. Firstly drill the hole.
  2. To set a rivet, the rivet is placed into the setting tool and then into a pre-drilled hole. It is fixed by the jaws within the tool pulling the mandrel head into the rivet body, expanding the body and causing it to flare against the reverse (blind) side of the application.
  3. As the head of the mandrel reaches the face of the blind side material, the mandrel will snap at the break point of the mandrel when it has reached is predetermined breaking force.
  4. A tight joint is formed as the rivet body remains, gripping the material and encapsulating the head of the mandrel within.
