An exclusive POP rivet design, this rivet type incorporates a unique cup-shaped end configuration that seals tight, preventing passage of vapor or liquid around or through the set rivet. In addition Closed-End Sealing POP Rivets provide up to 23% greater tensile strength than equivalent open-end typed. Finally these closed-end rivets provide 100% mandrel retention, and this can be an important factor in such applications as electric and electronic equipment. This rivet type is available with dome or countersunk head styles and with solid core or hollow core mandrel in a variety of material combinations including stainless.

Note: Closed-End product with a solid core reqiure a secondary grinding operation to the mandrel on the primary side of the application once the rivet has been set.
