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, POP closed-end sealing rivets provide up to 23% greater tensile strength than equivalent open-end rivets. Finally, these closed-end rivets provide 100% mandrel retention, which can be an important factor in applications such as electric and electronic equipment. This rivet type is available with dome or countersunk head styles in a variety of material combinations including stainless steel.
Note: Closed-end product with a solid core requires a secondary grinding operation to the mandrel on the primary side of the application once the rivet has been set.
