1/4" (#8) Blind Rivet Diameter with EPDM Neoprene Washer


  • 1/4" or #8 Diameter 
  • Trade Names: Tri Fold Rivets, Bulbing Rivets, Exploding Rivets, Tri Grip Rivets, Trailer Rivets, Expanding Rivets
  • Wildly popular in domestic appliances, plastic components, automotive, trailers, RV, kayaks and sporting goods.
  • Included Neoprene EPDM Washer to seal any gaps
  • Three anchor point grip adds resistance to pull though
  • Wider effective grip range - Excellent as a Multi-Grip Rivet
  • Caulk or sealant is recommended when installing to be truly watertight

Tri-Bulb Rivets expand in three directions as the mandrel is pulled through them, creating three anchor points on the blind end of the application. They have better retention than a standard pop rivet due to their increased surface area. These rivets also work better in thinner metals without causing damage to the materials.

Dome Head Tri-Fold Rivets create a finished look similar to a standard pop rivet, and do not require any special tools for installation (other than a standard riveter).
