Dome Head Closed End Blind Rivets

Dome Head Closed End Blind Rivets

Closed end blind rivet is also named sealed type blind rivet. As a strong and waterproof fastener solution, Closed end blind rivets provides 100% mandrel retention to prevent leakage of liquid or gas through the set rivet. Closed end rivets are used where adjacent backing plates are inaccessible but must be weatherproof. Closed end blind rivets also offer greater tensile and shear strength than open-end rivets and are often preferred for electronic applications because the mandrel cannot fall into the work area.

Closed end rivets permanently join two materials by inserting the rivet body into a hole, then using a rivet tool to pull the mandrel, causing the rivet body to expand. The pressure of the tool eventually pops off the mandrel, leaving behind the secured rivet.

Stainless steel 304 / Stainless steel 420 grooved dome closed end blind rivets features a grooved surface that provides superior grip for use with various materials. Features stainless steel 304 rivet body and stainless steel 420 mandrel. Stainless steel provides higher tensile and shear strength, resists corrosion and can withstand exposure to a wide range of chemicals and solvents. 

Diameter sizes from 3.2 to 6.4mm.
