About This Product

Rivets are a two-part fastener consisting of a shell and a headed stem (mandrel) assembled so the shell can be placed into the work to be fastened and are usually used to fasten soft metals and for decorative applications

How Rivets Work

The rivet is ‘set’ by drawing the stem through the shell, which causes the body to expand/compress to distort and clamp the material securely. After the desired clamping force is achieved, the stem breaks off at a predetermined position and is discarded. A small portion of the stem remains trapped in the bottom of the shell to ensure the clamping force is retained in the joint. Blind rivets are designed to clamp together specific thicknesses of material. If the grip range is less than it should be (the rivet is too long), excessive material will be left on the blind side and more pulls will be required to break-off the mandrel. If the grip range is too large (rivet is too short), insufficient material may be left on the blind side to secure the joint

  Frequently Asked Questions

  What is the tensile strength of this rivet?

  Yield 240 MPa, ultimate tensile 400 MPa. Mild-steel grade for general fastening below working limits.

  What does DIN7337 mean?

  DIN 7337 is the international standard for blind pop rivets.

  What thickness of material can this rivet fasten?

  This rivet's grip range is 3.3mm to 4.8mm — the total combined thickness of the materials you're joining must fall within this range. If the layers add up to less than the minimum, the rivet won't form a proper back-head; if more than the maximum, the mandrel won't pull through to set the joint.
